This study presents research on the forensic profiling of plastics that are often found on a crime scene. A novel standard was designed to improve quantitative polymer analysis using LA-ICP-TOF-MS, a powerful analytical technology that enables highly sensitive elemental analysis to be performed directly on solid samples.

The study shows the feasibility of using the novel standard for the quantitative analysis of chemical attribution signatures of trace elements in polymers by means of LA-ICP-TOF-MS. It significantly improves the classification and forensic comparison of polymer-based evidence.
