Generating actionable results at the sample site when processing data from portable mass spectrometers

In fifteen words or less, explain the significance of this contribution (Novel Aspect).: This presentation will demonstrate the significance of data processing methods for field portable MS spectrometers.

Abstract Text:

Portable mass spectrometry systems are extensively deployed, and the applications for these systems are quite variable. They are used for identification during space exploration, for the analysis of hazardous air pollutants by environmental scientists, for the detection of illicit drugs including potent synthetic opioids like fentanyl by law enforcement officers, for screening of air cargo for explosive residues, by hazardous materials response personnel at scenes where chemical threats are present, and even for the detection and identification of toxic chemicals in military theater. In some forms, like with gas chromatography-mass spectrometry, these systems can separate and isolate analytes for evaluation, which is helpful for samples with complicated matrices. However, even for gas chromatography-mass spectrometry systems, there are still challenges faced at the sample site when data is processed on board so that actionable information in real time is provided to the analyst. The ability to provide the operator with actionable information in real time is frequently the primary value of using a portable spectrometer in the field.  This presentation will review the status of on-board data processing when using mass spectrometers in the field and will consider how different types of data processing methods impact results. Special attention will be given to portable mass spectrometry instrument types including ion-traps, high pressure mass spectrometers, and gas chromatography-mass spectrometers (both ion trap and quadrupole systems).
