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...

Toxicology

Ongoing
Development of Low-Volume Drop Blood Drug Screening Tools This project aims to leverage recent NIST advances in ambient ionization mass spectrometry to develop platforms for low-volume blood drug screening. Direct Analysis in Real Time Mass Spectrometry (DART-MS) and Paper Spray Ionization Mass...

Trace Contraband Detection

Ongoing
Screening of people and their belongings including luggage, vehicles, and packages for the presence of trace residues of explosives and narcotics (trace contraband detection) is widely used in aviation security and law enforcement. In common screening scenarios, trace contraband residues in the form...

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...
