Applications of LA–ICP–MS to Forensic Science

Laser ablation inductively coupled plasma mass spectrometry (LA–ICP–MS) provides qualitative and quantitative measurements of the elemental and isotopic composition of materials that are of interest to forensic scientists. The technique can chemically characterize physical evidence associated with a crime event, a location, contact between objects or contact between objects and a person(s). This review details the forensic application of this powerful technique for the analysis of glass, soils, ink, paper and adhesive tapes, all important evidence that benefits from trace element profiling. In addition, other applications of LA–ICP–MS for forensic purposes are referenced, including food authentication, and gold and diamond provenance.
