Trace-Level Quantitation of Tear Gas Lachrymators in Complex Matrices

This Application Note demonstrates the excellent performance of GC×GC coupled with a BenchTOF time-of-flight mass spectrometer for the forensic analysis of tear-gas lachrymators. Analysis of a lachrymator standard is first shown to provide robust quantitation, and this is followed by the detection of capsaicin and dihydrocapsaicin at trace levels in a complex extract from contaminated clothing.
