In episode six of our 2019 NIJ R&D season, Just Science interviews Dr. Jorn Yu, professor at Sam Houston State University, about the chemical analysis of controlled substances using automated headspace solid phase microextraction.

Developed in the 1990s, headspace solid phase microextraction isn’t necessarily a novel technique. While it is a reliable method for extracting analytes, it hasn’t really found a home in the forensic sciences until now. With support from an NIJ Grant, Dr. Jorn Yu is combining this tried extraction method with Gas Chromatography Mass Spectrometry. Listen in as he discusses a method for identifying controlled substances using headspace solid phase microextraction and GC/MS in this episode of Just Science.
