Abstract
Detection apparatus including an IMS detector (1, 100) or the like has a gas inlet (10) with a gas flow path arrangement (40, 41, 102) by which sample gas is supplied to the detector. In one arrangement two regions (40 and 41) of a gas flow path arrangement are connected in parallel. The regions are provided by respective GC capillary tubing coils (40) and (41) coated internally with materials of different absorption characteristics so that the time taken for the chemical of interest to reach the detector (1) is different along the two coils, thereby giving responses in the detector at different times. Alternatively, two regions of a gas flow path could be provided by regions (104 and 106) arranged serially one after the other.
