Streamlined Elemental Analysis: Applications of Laser-Induced Breakdown Spectroscopy to Forensic Evidence

Presented by Dr. Tatiana Trejos
Thursday, July 26, at 11:00 AM (PST)

Advances in LIBS (Laser-Induced Breakdown Spectroscopy) technology have triggered a growing number of applications to detect and characterize elemental profiles of forensic evidence samples. These methods have the convenience to offer intrinsic real-time, minimal to none sample preparation, and high sensitivity and specificity. This web-seminar is meant to highlight some research that has been performed to date to enhance and speed up forensic examinations of materials using LIBS , including gunshot residues, questioned documents, and trace evidence.

Presenter:

Dr. Tatiana Trejos, Assistant Professor, Department of Forensic and Investigative Science, West Virginia University

Dr. Trejos’s research interests include chemical analysis of micro traces, mass spectrometric and spectroscopic chemical imaging, the discovery of chemical signatures of forensic materials for intelligence-driven applications and the use of chemometrics to forensic evidence interpretation. Previous research has included the development of spectrochemical methods (ICP-MS, Laser Ablation ICP-MS, u-XRF and Laser Induced Breakdown Spectroscopy) for the forensic analysis of glass, paint, documents (paper & ink), soils and tape evidence.
