Ion mobility spectrometry is best known historically for its use in homeland security. It is fast, robust, and transportable. Airports around the world rely on ion mobility for detection of explosives, most of which are highly ionizable compounds that give a strong response in these types of detectors.
Explosive detection is often done at mobile sites or at a location such as an airport where space is a valuable commodity. The compact size of the GA2100 standalone HPIMS instrument is ideal for this situation. The instrument can be set up on site and loaded with a database of common explosives of interest. Samples are analyzed in under one minute, and the library provides an answer as to whether explosives are present and if so, which ones.
High performance ion mobility spectrometry analyzes samples with a higher resolution than was previously possible with IMS instrumentation. This means that not only can compounds be detected, but they can be separated from other similar compounds. This could give more insight into what types of compounds are being used for chemical warfare, and could provide more accurate quantification data for detecting compounds at low levels.
