“…The applicability of TEA CO 2 laser based non-gated LIBS for spectrochemical analysis of various types of solid samples have already been investigated. [15][16][17][18][19] The aim of the present study was to demonstrate the adequacy of a non-gated TEA CO 2 LIBS system for quantitative analysis of trace elements in a powder/ /particulate cast iron samples in air at atmospheric pressure. All cast iron samples (certified standards and unknown samples) were obtained by participation in the 2 nd LIBS Inter-Laboratory comparison test "Powder/Particulate Cast Iron" in July-September 2016.…”

“…Nevertheless, for the analysis of a certain type of samples higher precision and sensitivity were obtained with CO 2 compared to Nd:YAG laser. [13][14][15][16] In the present study, a laboratory LIBS setup was used, in which the infrared pulsed transversely excited atmospheric (TEA) CO 2 laser is applied as the excitation source and time-integrated space-resolved detection scheme is used for the acquisition of emission spectra. The main benefit of this non-gated LIBS system, compared to commonly practiced LIBS, is simplification of the instrumentation and its cost.…”

The analytical capability of laser-produced plasma for the analysis of low alloying elements in cast iron samples has been investigated. The plasma was induced by irradiation of a sample in air at atmospheric pressure using an infrared CO 2 laser. Emission spectra were recorded by time-integrated spatially-resolved measurement technique. A set of ten cast iron samples in a powder or particulate form were provided by BAM (Bundesanstalt für Material Forschung und Prüfung, Deutschland), seven of which were used for calibration, and three were treated as unknowns. Linear calibration curves were obtained for copper, chromium, and nickel, with correlation coefficients above 0.99. Precision and accuracy of the LIBS method was evaluated and compared to those obtained by the inductively coupled plasma (ICP) analysis of the same samples. Detection limits for Cu, Cr and Ni were close to those reported in the literature for other comparable iron-based alloys obtained using different LIBS systems. Analytical figures of merit of the studied LIBS system may be considered as satisfying, especially in the light of other advantages of the method, like cost effective and fast analysis with no sample preparation, and with a possibility for real-time on-site analysis.

“…Basalt is a very important rock as it is the most common rock in Earth's crust and is also an abundant rock on other satellites and planets, for example, Moon and Mars [13]. TEA CO 2 laser-based LIBS has been previously applied for the analysis of basalt under simulated Martian atmospheric conditions (CO 2 gas; pressure: 9 mbar) [4]. It was shown that this LIBS system provides good analytical capabilities for geological studies under low-pressure CO 2 gas.…”

We present a study of the plasma generated by transversely excited atmospheric (TEA) CO2 laser irradiation of a basalt sample. The plasma was induced in air at atmospheric pressure. The same sample was also analyzed using a commercial LIBS system based on Nd:YAG laser and time-gated detection. The main plasma parameters, temperature, and electron number density were determined and analytical capabilities of the two systems compared. Despite differences in laser wavelength, pulse duration, applied fluence, and signal detection scheme, the two systems are comparable in terms of element detectability and limits of detection. In both cases, all elements usually present in geological samples were identified. The estimated limits of detection for most elements were below 100 ppm, while for Cu, Cr, and Sr they were around or below 10 ppm. The obtained results led to the conclusion that simple, cost-effective TEA CO2 LIBS system can find applications for geological explorations.
