Substances detection system and method

摘要

A system and methodology for the detection of threat substances is described. The detector system consists of a method to evaporate the sample into a primary separator and thermal release of trapped target materials into a secondary separator like conventional GC. The GC column is thermally ramped to elute all substances and the end of the column terminates into an atmospheric pressure chemical ionization source of an axial ion mobility spectrometer (AIMS). Both polarity ions are pulsed into a single construction separator tube at different timing. Their arrival time is detected on a collector plate, which allows registering their ion mobility spectra of both polarities for a single GC peak.

1. A system for detecting the presence of a plurality of predetermined analytes in a sample, the system comprising:
a temporal separation means for temporally separating the predetermined analytes, contained within the sample, from one another; an ion mobility spectrometer detector programmed to detect the predetermined analytes in the sample; wherein the temporal separation means is configured to deliver the predetermined analytes one by one, separated from one another in time, to the ion mobility spectrometer detector.
