Forensic Paint Comparison with J200 LIBS Instrument

Confident and Accurate Forensic Paint Comparison using J200 LIBS Instrument

Along with glass fragments, paint chips are valuable trace evidence for solving homicides, vehicular hit-and-runs, sexual assaults, and burglaries.  Forensic analysts have a new tool for examining paint with more accuracy than ever before. Laser Induced Breakdown Spectroscopy (LIBS) is a powerful analytical technology for comparing chemical formulation and layer structure between questioned and known sources of paint samples.

Request a copy of AppMan inspects car paint damagelied Spectra’s Application Note “Discrimination of Paint Samples by Laser Induced Breakdown Spectroscopy (LIBS)” and learn how the J200 LIBS Instrument helps distinguish among vehicle paint samples using unique fingerprint-like elemental spectra and depth profiling capabilities.

Applied Spectra would like to thank Mr. Edward “Chip” Pollock at Sacramento County District Attorney’s Crime Laboratory who was the guest author on this note. His insights and real-world examples of using LIBS for the forensic analysis of paint were immensely valuable and made this application note possible.
