AB  - A feature of Laser-Induced Breakdown Spectroscopy (LIBS), the ability to perform depth profiling, has been exploited to analyze a tungsten‑copper functionally graded material (FGM), considered a relevant candidate for components in a nuclear fusion reactor. The proposed method relies on establishing correlations between the depth of ablation craters and the number of laser pulses, along with the accompanying LIBS spectra acquired by varying a number of laser pulses. LIBS measurements were performed using a Q-switched Nd:YAG laser at 532 nm with 100 mJ/pulse energy under reduced Ar pressure. The ablation craters were analyzed using optical profilometry. The copper concentration at each specific depth was assessed using a univariate calibration curve constructed with intensity ratios of Cu I 521.82 nm and W I 522.47 nm spectral lines. The calibration samples were pure W and homogenous W/Cu composite samples with different Cu content (10.9% - 35.3%) whose composition was determined by X-ray fluorescence. The proposed method exhibits potential applicability for quantitative analysis of multilayered materials.

AB  - In this experimental study, picosecond laser treatment was performed on a nickel-based superalloy Nimonic 263, aiming to investigate the surface effects induced by irradiation in different atmospheric conditions and, concerning changes in surface composition, regarding the possibility for improvement of its functionality. Besides the varying laser parameters, such as a number of pulses and pulse energy, environmental conditions are also varied. All surface modifications were carried out in standard laboratory conditions and a nitrogen- and argon-rich atmosphere. The resulting topography effects depend on the specific laser treatment and could be categorized as increased roughness, crater formation, and formation of the laser-induced periodic surface structures (LIPSS). Changes in the chemical surface composition are distinguished as the potential formation of the protective oxides/nitrides on the sample surface. Numerous characterization techniques analyse the resulting effects on the topography and surface parameters. The multi-response parametric optimization of the picosecond laser process was performed using an advanced statistical method based on Taguchi’s robust parameter design. Finally, the optimal parameter conditions for Nimonic 263 modification are suggested.

AB  - Time-integrated optical emission analysis of laser-induced plasma on Teflon is presented. Plasma was induced under atmospheric pressure air using transversely excited atmospheric CO2 laser pulses. Teflon is a C-based polymer that is, among other things, interesting as a substrate for laser-induced breakdown spectroscopy analysis of liquid samples. This study aimed to determine the optimal experimental conditions for obtaining neutral and ionized C spectral lines and C2 and CN molecular band emission suitable for spectrochemical purposes. Evaluation of plasma parameters was done using several spectroscopic techniques. Stark profiles of appropriate C ionic lines were used to determine electron number density. The ratio of the integral intensity of ionic-to-atomic C spectral lines was used to determine the ionization temperature. A spectral emission of C2 Swan and CN violet bands system was used to determine the temperature of the colder, peripheral parts of plasma. We critically analyzed the use of molecular emission bands as a tool for plasma diagnostics and suggested methods for possible improvements.

AB  - In this study, plasma induced by a nanosecond Nd:YAG laser on thin oil films deposited on a silica wafer was characterized by evaluating the main plasma parameters. Spatially and temporally integrated spectral measurements were performed under experimental conditions optimized for elemental analysis of trace metals in oil. Time-resolved values of the spectral line intensities, electron number density, and plasma temperature were obtained from time-integrated measurements by subtracting averaged spectra recorded at different time delays. The electron number density was estimated using the Stark broadened profile of the hydrogen Balmer alpha line. Ionization temperatures were derived from Mg ionic to atomic line intensity ratios. The obtained apparent values of time-resolved plasma parameters were in the range of 1.1×1017 cm-3 (1.5 μs) to 1.5×1016 cm-3 (4 μs) and 9400 K (3 μs) to 7200 K (5 μs), depending on the delay time. Emission spectra of C2 and CN molecules were used to evaluate the rotational and vibrational temperature.

AB  - Austenitic stainless steel 316L finds a number of applications including filtration technology, nuclear industry, biomedicine, etc. Powder metallurgy (PM) allows obtaining the desired structure of the material, from full density to highly porous one, and PM technology most often comprises pressing and sintering steps. Gravity sintering, applied in this work, i.e. liquid phase sintering where the pressing step is excluded, is enabled by adding small amount of boron or its compound [1]. The addition of NiB lowers the sintering temperature by formation of eutectics (liquid phase), and also enhances mechanical properties (tensile strength, hardness) and corrosion resistance of 316L steel [2]. The aim of this work was to examine the surface behavior of PM-obtained 316L-NiB exposed to conditions of high heat fluxes by employing nanosecond laser pulses (TEA CO2 laser emitting at 10.6 μm, fluence ~14 J/cm2, intensity ~40 MW/cm2), which is reported scarcely in literature [3]. Simultaneously with irradiation in vacuum, plasma formed by laser irradiation above the sample surface was analyzed using LIBS (Laser Induced Breakdown Spectroscopy). Namely, small amount of boron (1 wt.% of NiB contains 83 wt.% of Ni and 17 wt.% of B) is not easily detected in gravity sintered sample and one of the techniques of choice could be the LIBS. For comparison purposes, 316L sample wihout NiB was also examined. Laser-irradiated surfaces were analyzed using SEM connected to EDX device. The damage was superficial, with intense melting in the central part of the irradiated spot, Fig. 1(a). LIBS analysis, Fig. 1(b), has shown successful in detecting the presence of boron in the 316L-NiB stainless steel, with low estimated limit of detection of 32 ppm.

AB  - This work presents a study of the applicability of laser-induced breakdown spectroscopy based on infrared transversally excited atmospheric CO2 pulsed laser for quantitative analysis of main inorganic elements in lignite coals. Calibration standards were prepared by mixing and pelleting an appropriate amount of rock reference material and graphite. Time-integrated spatially resolved measurements of analyte spectra of standard samples were used to construct univariate calibration curves of Al, Si, Ca, Fe and Mg. The spectral intensities of analytical lines were normalized by the carbon spectral line to compensate for the shot-to-shot fluctuation of plasma parameters. The obtained curves of growth have good linearity in a wide range of concentrations (up to 1% for Al and 3% for Si). Correlation coefficients were in the range of 0.955–0.993, depending on the element. Measured limits of detection (from 2.4 to 25 ppm for analyzed metals and 61 ppm for Si) are low enough to control the coal combustion process in power plants. The Stark-broadening and the Boltzmann plot method were used to determine apparent values of excitation temperatures and electron number densities. A relatively small but measurable influence of the concentration of metal elements on the plasma parameters was observed, which should be considered in quantitative analysis of coal samples with higher inorganic elements content.

AB  - The surface of a titanium-based alloy Ti6Al4V was subjected to modifications by a near-IR femtosecond Ti:Sapphire laser, emitting at 775 nm pulses of 200 fs duration, in single-pulse and multi-pulse regimes, with up to 400 accumulated pulses, and pulse energies ranging from 2.5 to 250 $$\upmu $$J. The whole range of induced effects is presented, from gentle ablation and pattern occurrence to substantial crater formation. Very observable laser-induced parallel periodic surface structures are reported, appearing both within the damage spot area, with low fluences, and at the peripheries of the craters, with higher fluences—but also on crater walls, and inside the crater structures. Damage threshold fluences $$({F}_{\mathrm{th}})$$and the incubation factor $$(\zeta )$$were also determined.

AB  - In this study, the design of surface pattering with the co-existence of micrometer and nanometer features was carried out to improve the arrayed surface structures on Ti/Cu/Ti and Ti/Cu/Zr/Ti multilayer thin films by picosecond laser processing. The novel composite structure consisted of two layers of Ti and subsurface distributed Cu and Zr layers (thickness of 10 nm) were deposited by ion sputtering on Si substrate to the total thickness of 300 nm. The changes in the composition, surface morphology, and wetting properties after laser modification was monitored by Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM–EDS), optical profilometry, and wettability measurements. It was found that laser irradiation can induce the melting of material with the formation of wrinkled periodic structures at the edges of the laser spots in both systems as a consequence of the hydrodynamic effects. Another interesting result was that the periodic structure in form of LSFL (low spatial frequency LIPSS) ripples was numerous but slightly pronounced in Ti/Cu/Zr/Ti, due to the presence of the Zr component as an ultra-thin subsurface layer, which most likely favored creating LIPSS. Such laser texturing has been used in the biomedical field as a method of developing surface topography, coated with oxides to potentially improve cell response via suitable surface wetting for a biological system.

AB  - The interaction of a Transversely Excited Atmospheric (TEA) CO2 laser with a polymer polymethyl methacrylate (PMMA) sample in a vacuum ambiance was studied. The main goal was to demonstrate the feasibility of laser-induced breakdown spectroscopy (LIBS) to detect hydrogen. The generation of plasma over the PMMA surface, using a low laser intensity of ∼ 48 MW/cm2 and fluence of ∼ 16.5 J/cm2, required the application of a metal sub-target. Besides hydrogen, the recorded spectra were dominated by atomic lines of carbon and oxygen and band emission of the C2 and CN molecules. The electron number density and temperature (ionic, vibrational, and rotational) were evaluated to characterize the laser-induced plasma. In addition, PMMA micro-damages (diameter ∼ 45 µm) created by a multipulse laser ablation could find potential applications in sensor technologies.

AB  - The analytical potential of LIBS for the analysis of liquid solutions was evaluated using two experimental setups, one based on a TEA CO2 laser and the other in which Nd:YAG laser was used. Polytetrafluoroethylene (PTFE) was used as a substrate on which a 10 μL drop of analyte solutions with different concentrations of analyte elements, Be, Cr, Ni, Co, Pb, Tl, and V, were deposited and dried. The samples were deposited either directly on the PTFE or over the pre-deposited layer of copper oxide nanoparticles to study the influence of nanoparticles (NPs) on the ablation and plasma excitation. The obtained results imply that the presence of Cu oxide NPs does not significantly affect the analytical performance of LIBS based on TEA CO2 laser for analysis of solutions. At the same time, it was shown that plasma created by TEA CO2 laser radiation efficiently excited ablated material, making metal elements detectable in the sub-ppm concentration range. On the other hand, Cu oxide NPs significantly influence the formation and the analytical properties of plasma induced by Nd:YAG laser. Without the presence of NPs, the intensities of analyte lines were very low, unsuitable for spectrochemical analysis. At the optimal surface concentration of NPs, 0.36 mg/cm2, the intensity of analyte lines was increased more than ten times. Limits of detection of Be and Cr were 5.3 ppb and 33 ppb, with good linearity of curves of growth.

Estimated limits of detection (LODs) for Ni, Co, and Cr, were 2.1, 3.2, and 0.4 ppm, respectively. In addition, two main plasma parameters, electron number density and temperature, were determined to characterize the laser-induced plasma. The electron number density (Ne) was determined from the measured Stark width of the Al I 396.15 nm line, and the intensity ratio of two atomic iron lines (342.71 nm and 344.06 nm) was used to determine the excitation temperature (Texc). The obtained values were Ne= 8.3·1016 cm-3 and Texc= 7700 K.

AB  - The aim of this study was to demonstrate the potential of Laser-Induced Breakdown Spectroscopy (LIBS) in the analysis of pottery shards, which are commonly the most abundant artefacts recovered at archaeological sites. The analytical capability of LIBS in identification of elements characteristic to inorganic pigments used for decoration was assessed. Based on the specific elements detected in the LIBS spectra of glazes, correlations between the elemental composition of the glaze and the colours of the glazed surface were established. The results were in accordance with the previously reported Energy Dispersive X-ray Fluorescence (EDXRF) and Raman analyses of some of the samples, and with the presently performed XRF analysis. Two important parameters for plasma characterization, temperature and electron number density, were estimated from the spectral data. A potential use of LIBS for depth profiling was also investigated by analysing the silicon to aluminium intensity ratio as a function of the number of laser shots applied. Profilometry analysis of the damages created on the glazed surfaces by laser shots was used to estimate the average ablation depth and ablated mass.

AB  - Design of surface patterning with the co-existence of micro- and nanoscale features by picosecond laser processing is investigated in order to improve cell integration. New biomedical Ti alloys with a high concentration of β-stabilizer elements (zirconium) are developed, as potential solutions to the mismatch between the Young’s modulus of the implant and the surrounding hard tissues. On the other hand, in order to enhance the tribological and antimicrobial properties of Ti/Zr coating, a novel titanium-copper and titanium-copper-zirconium thin film systems were designed in this work. Novel composite structure composed of subsurface distributed Cu and Zr layers (thickness of 10 nm), with satisfying mechanical properties and moderate biocompatibility, were deposited by ion sputtering on Si substrate to the total thickness of 300 nm. The multilayer thin films were irradiated by focused linearly p-polarised picosecond pulses with follow characteristics: repetition rate of 10 Hz, pulse duration equal to 150 ps, central wavelength of 1064 nm and 120 µm Gaussian spot diameter. The changes of the composition and surface morphology in the Ti/Cu/Ti/Si and Ti/Cu/Zr/Ti/Si multilayer thin films were monitored by X-ray photoelectron spectroscopy (XPS), by scanning electron microscopy (SEM) and by profilometry. The main part of the absorbed laser energy was rapidly transformed into heat, producing intensive modifications of composition and morphology on the multilayer surface [1,2]. The results show an increase in surface roughness, formation of a specific surface topography, appearance of hydrodynamic features and ablation of surface material. XPS analysis revealed that laser modification was induced intermixing between the Cu and Zr layers, but also with dominant Ti component. During the laser processing of Ti/Cu/Ti/Si and Ti/Cu/Zr/Ti/Si multilayer thin films, delivered energy was sufficient to cause solid-state reactions, the formation of alloy between components. Laser processing of Ti/Cu/Ti/Si and Ti/Cu/Zr/Ti/Si multilayer thin films is used to create the arrayed surface structure, such as laser-induced periodic surface structures (LIPSS) and at the same time to induce mixing of components inside the thin film structures, as well as the formation of ultrathin oxide layer at the laser-treated surfaces [3,4]. Laser surface patterns are organized as networks and parallel lines, where lines formed of LIPSS are wide up to 100 μm and distance between lines are less than 300 μm. The average periodicity between LIPSSs was about 900 nm, which would correspond to the formation of low spatial frequency LIPSS (LSFL).

AB  - The application of laser-induced breakdown spectroscopy (LIBS) for the elemental analysis of pig shoulder bone samples is reported. Measurements were performed using a compact laboratory-made TEA CO2 laser with low pulse energy. The recorded spectra consisted of well-defined lines of atoms and single charged ions of Ca, Mg, P, and other constituent elements, with a good signal-to-noise ratio suitable for spectrochemical analysis. Based on the ICP quantitative analysis of the bone sample, the limits of detection of LIBS analysis were estimated for Mg (16 ppm) and Na (940 ppm). Plasma parameters, temperature, and electron number density were determined by measuring Stark widths and relative intensities of the C and Mg ionic and atomic spectral lines.

AB  - For elucidation a possibility to use molecular emission spectra in LIBS analysis of carbon containing materials time and space resolved spectra of laser ablation plasma from graphite were studied. Laser plasma was produced on a rotated graphite target by fundamental harmonic of YAG: Nd3+ laser (Lotis TII) in air at atmospheric pressure. The optical emission spectra were analyzed using a GSM850 Lotis TII monochromator/spectrograph equipped with a CCD detector. The atomic and molecular spectra in the region of emission of molecules C2 (λ = 516,52 nm) and CN (λ = 421,16 nm) were registered by photomultiplier placed behind the interference filter to record the intensity of the selected plasma emission line. The temporal and spatial characteristics of the plasma spectra with special attention to molecular carbon including molecules СN and С2 were analyzed. It was found that the time range of dominance of the C2 and CN emission is related to the stage of the plasma decay (10–20 μs after the action of the laser pulse, depending on the conditions for plasma creating). The atomic emission spectra of the plasma were used to estimate the concentration of electrons and the electron temperature of the plasma. The vibrational temperature of the carbon plasma was determined from the molecular spectrum of the radical СN ((∆ν = 0, -1). The plasma electron concentration and electron temperature as well as vibrational temperature were determined in different zones of the expanding plasma and at different values of laser power densities (2,2·108 ÷ 3,7·108 W/cm2 ) used in experiments. The electron temperature varied in the range 9700 – 10300 K, the electron concentration was estimated to be in the range from 0,8·1018 cm-3 to 8,0·1018 cm-3 , the vibrational temperature of the plasma was 4560 - 7350 K depending on the experimental conditions (laser power density, spatial zone of the plasma plume).

AB  - The purpose of this study was to examine the accumulation potential of spontaneously developed Tussilago farfara populations colonizing sites with different levels of anthropogenic pollution. Physical characteristics of the soil are presented, together with the concentrations of macroelements and microelements (Ca, Mg, Fe, S, Al, Pb, Zn, Cu, Cd, Mn, As, Sb, Ag, Ti, and Sr) in both soil and plants. The biological concentration, accumulation, and translocation factors were used to assess the potential for heavy metal accumulation. Considerable differences were found among assessions from unevenly contaminated habitats, particularly in comparison with an unpolluted site. In line with the ore’s characteristics, substrate samples from polluted sites were heavily contaminated with Pb, Zn, As, and Sb. Increased levels of microelements were also detected in plant samples from flotation tailings. Despite active absorption of Zn, Cu, Cd, Mn, and Sr by the plants from mining sites, the detected quantities of these elements in all samples were below the hyperaccumulation threshold. However, the obtained results indicate that the use of T. farfara from such sites in traditional medicine could pose a risk to human health due to accumulation of several toxic elements in the plant’s aboveground tissues. Additionally, as a successful primary colonizer and stabilizer of technogenic substrates, T. farfara has an important role in the initial phases of revegetation of highly contaminated sites. © 2019, Springer-Verlag GmbH Germany, part of Springer Nature.

AB  - This study investigated invasive Ambrosia artemisiifolia from five localities with different levels of anthropogenic pollution in order to determine the potential for accumulation of trace metals and metaloids. Physical characteristics of the soil are presented, together with concentrations of As, B, Ba, Ca, Cd, Co, Cu, Fe, Mg, Mn, Mo, Ni, Pb, Sb, Sr, and Zn in both plant and soil. The tested samples displayed considerable differences in element concentrations, depending on the level of anthropogenic activities, with the highest concentrations of elements observed in samples from Stolice and Piskanja, the sites with most intensive human influence. A trend of shoot accumulation can be observed in A. artemisiifolia, but without hyperaccumulation, along with lower root concentrations in almost all analyzed samples. This may pose an additional environmental risk, as accumulated elements can spread to other components of the ecosystem. While A. artemisiifolia acumulates a high and even toxic rate of B in shoots regardless of boron concentration in soil, there is a high correlation of Ba, Pb, and Zn concentrations in species shoots with their respective concentration in the soil. Successful colonization of both natural and anthropogenically polluted habitats indicates high tolerance of A. artemisiifolia, which complements its wide environmental amplitude.

AB  - Laser-induced breakdown spectroscopy (LIBS) is a diagnostic technique based on optical emission spectroscopy, suitable for rapid, in situ, and multi-element analysis of all sample types. LIBS has demonstrated its greatest potential in the analysis of solids, both conducting and nonconducting. However, when it comes to quantitative LIBS analysis of liquids, there are still some drawbacks that limit its applicability, such as poor repeatability and low sensitivity. To some extent LIBS performance may be improved if directly performing LIBS on the solution is avoided by converting the liquid into a solid phase. Another recently proposed method to resolve the difficulties in LIBS analysis of liquid samples is the application of Nanoparticle - Enhanced LIBS (NELIBS) [1,2]. The aim of the present work was to examine the effect of copper oxide nanoparticles (NPs) on the analytical capabilities of LIBS analysis of lead in aqueous solutions. The apparatus for NELIBS experiments comprises a laser source, a spectrograph (F=850 mm, grating 1800 groves/mm, F/11) coupled with a CCD, and the focusing and collecting optics, i.e. the same as used in conventional LIBS. A double pulse Q-switched Nd:YAG laser at 1064 nm, pulse duration 10 ns, pulse energy 50 mJ, interpulse delay 1 μs was used. The spectra were registered in a time-integrated mode (integration time 1 ms). A glass plate was chosen as the substrate to ensure there is no interference between NPs and the substrate. The first type of samples was prepared by drying a droplet of a Pb solution (10 μl, concentration 100 ppm) on the glass substrate. The second type was prepared by drying a droplet of the copper oxide colloidal solution on the glass, prior to the deposition of the analyte solution. Three sets of the LIBS spectra were acquired; spectra of glass with deposited CuO NPs, of glass with deposited sample solution of Pb, and of the glass with deposited NPs of CuO and the sample solution of Pb. The spectra were obtained in the 395-415 nm spectral range. Only in the third case, intense Pb lines appeared in the spectrum. Estimation of the limit of detection (LOD) for the resonance Pb line at 405.78 nm, without additional optimization of the measurement parameters, gave a value of 3.6 ppm. Regarding the fact that without the addition of the NPs layer no analyte signal was obtained, it can be concluded that the enhancement of the lead emission line intensity is caused by the presence of the NPs, i.e. by the lower plasma formation threshold and more efficient atomization of the analyte deposited on the NP layer. The main benefits of using NELIBS for the analysis of solutions lie in its simplicity, speed, the small amount of solution needed (few microliters), and the ability to analyze very dense or slurry samples.

AB  - Optical emission studies of graphite plasma induced by infrared (IR) Transversely Excited Atmospheric carbon dioxide (TEA CO2) laser pulses in ambient air at atmospheric pressure are reported. The plasma was induced at relatively low-irradiance, up to 40 MW cm−2, and the plasma emission was recorded using time-integrated LIBS measurements. The time profile of the 160 mJ laser pulse is composed of a short, 100 ns long initial spike, and a long 2 μs tail. About 60 mJ is contained in the initial pulse, and the 100-mJ tail contribution is favorable for extended plasma absorption that promotes creation of long-lasting highly-excited plasma. With laser pulse focused behind the target surface, recorded spectra consisted of intensive, sharp atomic and single charged ionic spectral lines of carbon, and trace elements, e.g. Ca, Cu, V, Si, and Ti. Good signal to background ratios obtained indicate potential application in the analysis of impurities in graphite, and also elemental analysis of other materials with high carbon content. The average electron number density was determined from Stark-broadened emission profile of C I 247.9 nm line, and the line intensity ratio of CII 250.9 nm/C I 247.9 nm line pair was used for estimation of ionization temperature. Depending on the applied fluence, electron density was in the range 2.6–4.8 × 1017 cm−3, and ionization temperature between 19,000 and 22,000 K. Beside line spectra, intensive and well-developed band spectra of diatomic molecules C2 (Swan system), and CN (violet system) were obtained. Pulse energy threshold for observation of molecular emission was 50 mJ. From the spectroscopic studies of the emission bands, the rotational and vibrational temperatures were estimated by comparing the experimental and simulated emission spectra. Vibrational and rotational temperatures deduced from Δν = 0 sequences of the Swan system of C2 were 3100 K and 3850 K, respectively. The most intense band of the CN violet system showed strong self-absorption and led to overestimated temperature values, Tvib = Trot = 4900 K. © 2019 Elsevier B.V.

AB  - Time-integrated optical emission spectroscopy was applied for the analysis of emission spectra, and determination of electron densities and excitation temperatures of basalt plasma induced by 10.6 micron laser radiation. The plasma was studied in air, argon and carbon dioxide, under pressure of 10, 50, and 100 mbar. The plasma emission intensity was found to be strongly dependent on the nature of the ambient gas and its pressure. The highest emission intensities and signal to noise ratios were obtained in argon. Depending on the composition and pressure of the surrounding atmosphere, the values of plasma temperature varied between 14,400 K (air at 10 mbar) and 17,100 K (carbon dioxide at 100 mbar). Similarly, the electron number density varied between 3 × 1016 cm−3 (10 mbar air) and 1.6 × 1017 cm−3 (100 mbar CO2). The observed behavior was correlated with the properties of the studied gases, in particular, their mass, thermal conductivity and ionization energy, and the role of the ambient gas in controlling the efficiency of laser-target coupling, laser-plasma interaction and plasma shielding. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.

AB  - Spektroskopija laserski indukovane plazme (Laser Induced Breakdown Spectroscopy, LIBS) je savremena metoda hemijske analize koja koristi optički signal iz laserski generisane plazme za proučavanje sastava materijala. LIBS se može koristiti za analizu uzoraka različite prirode i porekla zbog čega je našao primenu u brojnim oblastima [1]. U oblasti zaštite životne sredine LIBS je pogodan za brzu analizu opasnih metala i drugih zagađivača u vodi, zemljištu, biljkama, vazduhu, kao i za analizu otpada. Ono što posebno izdvaja LIBS od drugih spektrohemijskih metoda je mogućnost detekcije svih hemijskih elemenata iz periodnog sistema, uključujući i lake elemente (He, Li, Be, B, C, N, O...) koji se teško određuju drugim tehnikama, analiza čvrstih uzoraka bez potrebe za pripremom uzoraka, kao i mogućnost analize u realnom vremenu (in situ, stand-off, remote). Posebno treba istaći da se LIBS uklapa u koncept zelene analitičke hemije koja je prepoznata kao ključni deo zelene hemije [2]. Razvoj zelene analitičke hemije ima za cilj smanjenje negativnog uticaja hemijskih analiza na životnu sredinu. Najvažniji izazov za budućnost ove discipline jeste postizanje kompromisa između poboljšanja kvaliteta rezultata i povećanja ekološke prihvatljivosti analitičke metode. Danas, spektroskopske metode dominiraju u oblasti zelene analitičke hemije, a među njima posebno se, svojim karakteristikama i univerzalnošću, izdvaja LIBS. U najvećoj meri LIBS ispunjava postavljene principe zelene analitičke hemije koji razmatraju kompletan analitički proces koji uključuje uzorkovanje, pripremu, kao i sam proces analize uzoraka [2,3]. LIBS karakteriše velika fleksibilnost instrumentalne postavke. U zavisnosti od željene namene, optimizacija LIBS sistema može se postići izborom lasera određene energije, vremenskog trajanja laserskog impulsa (nanosekundni, pikosekundni, femtosekudni), kao i talasne dužine zračenja (ULJ, VID, IC). U praksi uobičajeno se koristi LIBS sistem koji se sastoji iz Nd:YAG lasera, spektrometra i detektora sa vremenskom rezolucijom. U okviru Laboratorije za fizičku hemiju INN Vinča razvijena je originalna LIBS aparatura koja se bazira na TEA (Transverzalno Ekscitovanom Atmosferskom) CO2 laseru, Slika 1. Ovaj kompaktni, impulsni, nanosekundni laser, koji je takođe kompletno konstruisan u INN Vinča, radi u visoko multimodnom režimu i emituje zračenje u infracrvenom delu spektra na 10,6 µm. Analitička primena laserski indukovane plazme zahteva optimizaciju, odnosno razdvajanje intenziteta kontinualnog zračenja od intenziteta linijske emisije analita u cilju postizanja zadovoljavajućih granica detekcije za posmatrani element. Za razliku od komercijalno dostupnih LIBS aparatura u kojima se koristi vremensko razlaganje signala, u ovoj eksperimentalnoj postavci optimizacija je postignuta alternativnom metodom, korišćenjem vremenski-integraljene prostorno-razložene laserske spektroskopije. Na ovaj način izbegnuto je korišćenje generatora kašnjenja i skupih iCCD detektora. Dosadašnja istraživanja vezana za analizu različitih tipova uzoraka pokazala su da je LIBS sistem koji koristi impulsni CO2  laser po analitičkim performansama (selektivnost, osetljivost, granice detekcije) u potpunosti uporedljiv sa komercijalnim LIBS uređajima, u odnosu na koje je naš sistem znatno kompaktniji, robusniji i ekonomski isplativiji [4-6]. Kompaktnost LIBS-a je posebno značajna jer manji broj komponenti olakšava konstrukciju prenosivog LIBS uredjaja. Tekuća istraživanja usmerena su na optimizaciju TEA CO2 LIBS-a za detekciju zagađenja vode i zemljišta teškim metalima.

AB  - In this study, analytical capability of Laser Induced Breakdown Spectroscopy (LIBS) system based on Transversely Excited Atmospheric pressure (TEA) CO2 laser for determination of elemental composition of tea samples was demonstrated. Analysis of LIBS spectra indicated emission lines attributed to the elements Fe, Mg, Cu, Ca, Al, Mn, Ba, P, K and Sr. For quantitative analysis of Mn and Ba, a standard addition method was employed. Linear calibration curves with regression coefficients exceeding 0.95 were obtained. The accuracy of LIBS results was confirmed by inductively coupled plasma optical emission spectroscopy (ICP-OES) analysis. Calculated recoveries for Ba and Mn were 99.7 and 102.3%, respectively. The results presented confirm the suitability of the proposed LIBS setup for rapid quantitative analysis of tea, while at the same time simplifying the overall analytical procedure. This approach can be easily used as a helpful analytical tool for food quality and safety control. (C) 2017 Elsevier B.V. All rights reserved.
