Forensic scientists generally require fast and non-destructive analysis of a very wide range of materials. Often these materials are presented in very small quantity, as evidence collected from a crime scene.
The elemental ‘fingerprint’ which XRF reveals is used to identify unknown materials, match crime scene materials to those found on suspects and provide vital information on explosive/gunpowder constituents.
The XRF method can identify a vast number of elements simultaneously it is an excellent tool for fingerprinting all kinds of materials analyzed in forensic analysis. Here are a few examples of material:
Paint, Glass, Ceramics, Metal, Soil, Plastic, Fabrics and Toxic Metals.
