Non-targeted screening in forensics, a discussion of method development and screening of forensic samples using GCXGC-TOFMS

Referenznummer: 2024nts04
Joining us from William and Mary, Dr. Katelynn A. Perrault Uptmor, PI of the Nontargeted Separations Laboratory , present her work of screening samples using comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (GCXGC-TOFMS) in forensic applications as novel types of evidence appear. Dr. Perrault Uptmor highlights initial approaches to method development for new samples and show recent applications related to chemical profiling of deposited fingermarks, organic gunshot residue and decomposition odor. She also discusses the implications of GCXGC-TOFMS sample visualization in the context of expert testimony for communicating screening processes in forensic casework within the courtroom.
