Vapor Sampling to Support Public Safety and Forensics

Ongoing
Vapor pressures of unstable, reactive compounds. Over the last decade, our group has investigated a variety of low-volatility compounds including taggants (found in explosives), biofuels, terpenes and cannabinoids. Dynamic vapor microextraction (DVME), developed at NIST, is a small-volume dynamic

Thermal Desorption Ambient Mass Spectrometry

Ongoing
The Surface and Trace Chemical Analysis Group is involved in a number of research avenues for the rapid screening of wipe-collected samples for the security and forensic chemistry fields. Similar to the widely-deploy ion mobility spectrometry (IMS) systems for screening, this is accomplished through
