Analysis of Trace Particulate Explosive Simulants by an Atmospheric Solids Analysis Probe (ASAP®) on the expression CMS

Overview:
Direct sample analysis is possible via an Atmospheric Solids Analysis Probe (ASAP®) combined with atmospheric pressure chemical ionization (APCI) on a compact mass spectrometer. This technique allows for the rapid investigation (<30 sec) of material suspected of containing trace amounts of explosive residues.

The expression Compact Mass Spectrometer (CMS) with an Atmospheric Solids Analysis Probe (ASAP®) is a high performance instrument with a small footprint that allows for efficient liquid and solid screening at the point of need. The CMS provides rapid and accurate detection with significantly reduced false-positives and false-negatives than other techniques.

Here, we demonstrate the use of the ASAP probe and expression CMS detector for explosives screening. Sampling via the ASAP probe is then inserted in to the APCI source of the mass spectrometer, initiating in a fast ionization reaction that provides rapid results.
