Optimization of Confined DART-MS

February 14, 2020
Author(s)
Edward R. Sisco, Matthew E. Staymates, Thomas P. Forbes
The use of direct analysis in real time mass spectrometry (DART-MS) is seeing increased use in a number of fields, including forensic science, environmental monitoring, food safety, and healthcare. With the increased use, novel configurations have been

Emerging techniques for the detection of pyrotechnic residues from seized postal packages containing fireworks

January 24, 2020
Author(s)
John Gillen, Thomas Forbes, Jennifer R. Verkouteren, Shannon T. Krauss, Karlijn Bezemer, Arian C. van Asten, Peter J. Shoenmakers, Mattijs Koeberg
High volume screening of parcels with the aim to trace the illegal distribution and selling of fireworks using postal services is challenging. Inspection services have limited manpower and means to perform extensive visual inspection. In this study, the

Discriminative potential of ion mobility spectrometry for the detection of fentanyl and fentanyl analogues relative to confounding environmental interferents

September 27, 2019
Author(s)
Thomas Forbes, Jeffrey Lawrence, Jennifer R. Verkouteren, R. Michael Verkouteren
The opioid crisis and emergence of fentanyl, fentanyl analogues, and other synthetic opioids has highlighted the need for sensitive and robust detection for interdiction at screening points, notably vehicles at border crossings and packages at postal

Review of the National Institute of Standards and Technology Research Program in Trace Contraband Detection

J Greg Gillen, Jennifer R. Verkouteren, R. Michael Verkouteren, Marcela Najarro, Edward Sisco, Matthew Staymates, Jessica L. Staymates, Robert A. Fletcher, Jeffrey Lawrence, Elizabeth Robinson, Alexander T. Bulk, Joe Bennett, Shin Muramoto, Thomas Forbes
Current national priorities in homeland security have led to an unprecedented level of utilization of explosives trace detection (ETD) systems for counterterrorism and law enforcement. Despite the widespread deployment of ETD instruments at airports

Recent Advances in Ambient Mass Spectrometry of Trace Explosives

May 6, 2018
Author(s)
Thomas Forbes, Edward Sisco
Ambient mass spectrometry has evolved rapidly over the past decade, yielding a plethora of platforms and demonstrating scientific advancements across a range of fields from biological imaging to rapid quality control. These techniques have enabled real

DART-MS analysis of inorganic explosives using high temperature thermal desorption

May 4, 2017
Author(s)
Thomas P. Forbes, Edward R. Sisco, Matthew E. Staymates, John G. Gillen
An ambient mass spectrometry (AMS) platform coupling Joule heating thermal desorption (JHTD) and direct analysis in real time (DART) was developed, generating discretely pulsed rapid heating ramps and elevated temperatures for the detection of inorganic
