Elemental Analysis of Glass by SEM-EDS, XRF, EPMA, LIBS and LA-ICPMS

This extension of research will address: 1) Standardization of a LIBS protocol for the analysis of glass and publication of such a protocol in the scientific literature; 2) Evaluation of Interpretation of the results for both LIBS and uXRF data analysis; 3) Development of match criteria for casework comparisons using either LIBS or uXRF data based on the evaluation of the interpretation results; 4) Presentation of these results at the upcoming Trace Evidence symposium. By following standard protocols and match criteria for glass examination, trace evidence examiners will be better suited to make efficient and accurate comparisons of glass samples. This will assist them in completing forensic casework, thereby reducing backlog.
