LA-ICP-MS is an elemental and isotopic microanalytical technique that has
found a place in several scientific fields, including Forensic Science. It can
chemically characterize physical evidence associated with a crime event, a
location, contact between objects, or contact between objects and a per-
son(s). The main forensic application of this technology is the analysis of
glass and paint samples. However, applications to other samples like docu-
ments (ink and paper), fiber, and gems have also been reported.
