“…In the case of forensic glass analysis, LIBS was determined to provide the same power of discrimination between different glass sources as either µXRF or LA-ICP-MS [10]. In the current work, correlation coefficients of > 0.990 were achieved for calibration curves for the trace elements analyzed in the range between 32 and 4600 ppm.…”

“…LIBS is an emerging method of atomic emission spectroscopy proving to be a viable alternative for the elemental characterization of forensic glass samples [10,11]. The advantages of LIBS have been clearly established and include the ability for real time analysis, little-to-no sample preparation or destruction, ease of use, low cost, and simultaneous multi-element detection without the need to know the element menu to be analyzed.…”

The public reporting burden for this collection of information is estimated to average 1 hour per response, including the time for reviewing instructions, searching existing data sources, gathering and maintaining the data needed, and completing and reviewing the collection of information. Laser Induced Breakdown Spectroscopy (LIBS) can be used for the chemical characterization of glass to provide evidence of an association between a fragment found at a crime scene to a source of glass of known origin. Two different laser irradiances, 266 nm and 1064 nm, were used to conduct qualitative and quantitative analysis of glass standards. Single-pulse and double-pulse configurations and lens-to-sample-distance (LTSD) settings were optimized to yield the best laser-glass coupling. Laser energy and acquisition timing delays were also optimized to ABSTRACTLaser Induced Breakdown Spectroscopy (LIBS) can be used for the chemical characterization of glass to provide evidence of an association between a fragment found at a crime scene to a source of glass of known origin. Two different laser irradiances, 266 nm and 1064 nm, were used to conduct qualitative and quantitative analysis of glass standards. Single-pulse and double-pulse configurations and lens-to-sample-distance (LTSD) settings were optimized to yield the best laser-glass coupling. Laser energy and acquisition timing delays were also optimized to result in the highest signal to noise ratio. The crater morphology was examined and the mass removed was calculated for both the 266 nm and 1064nm irradiations. The analytical figures of merit suggest that the 266 nm and 1064 nm wavelengths are capable of good performance for the forensic chemical characterization of glass. The results presented here suggest that the 266 nm laser produces a better laser-glass matrix coupling resulting in a better stoichiometric representation of the glass sample. The 266 nm irradiance is therefore recommended for the forensic analysis and comparison of glass samples.

“…10 Due to their attractive and important applications, laser-induced plasma produced from different glass types, such as fixation nuclear waste products by vitrification, are of great interest. 7,[21][22][23][24] High level liquid radioactive waste (HLW) is generated during reprocessing of spent fuel in a fuelreprocessing plant. For fixation, the HLW and the base glass frit are added to a furnace in a predetermined ratio and melted at a temperature of about 1000…”

Homogeneity testing and quantitative analysis of manganese (Mn) in vitrified Mn-doped glasses by laser-induced breakdown spectroscopy (LIBS)

et al. 2014

Laser-induced breakdown spectroscopy (LIBS), an atomic emission spectroscopy method, has rapidly grown as one of the best elemental analysis techniques over the past two decades. Homogeneity testing and quantitative analysis of manganese (Mn) in manganese-doped glasses have been carried out using an optimized LIBS system employing a nanosecond ultraviolet Nd:YAG laser as the source of excitation. The glass samples have been prepared using conventional vitrification methods. The laser pulse irradiance on the surface of the glass samples placed in air at atmospheric pressure was about 1.7×109 W/cm2. The spatially integrated plasma emission was collected and imaged on to the spectrograph slit using an optical-fiber-based collection system. Homogeneity was checked by recording LIBS spectra from different sites on the sample surface and analyzing the elemental emission intensities for concentration determination. Validation of the observed LIBS results was done by comparison with scanning electron microscope- energy dispersive X-ray spectroscopy (SEM-EDX) surface elemental mapping. The analytical performance of the LIBS system has been evaluated through the correlation of the LIBS determined concentrations of Mn with its certified values. The results are found to be in very good agreement with the certified concentrations.

“…However, within the last few years, three studies were published regarding the utility of this technique for forensic glass comparisons and each had a different approach (especially in terms data analysis). The short list includes some of the work presented in this dissertation, which also appears in a publication regarding the discrimination potential of LIBS [46]. Research presented by Rodriguez-Celis et al…”
