Abstract
A chemical sampling apparatus including an interface between a miniature mobility spectrometer and a gas chromatography system. The apparatus has a gas chromatography an ion mobility spectrometer and an input for inputting a regulated flow of a gas to be analyzed to the gas chromatograph. An interface is positioned between the gas chromatograph and the ion mobility spectrometer. The interface accepts and analyzes eluted gas from the gas chromatograph and selectively inputs the eluted gas to the ion mobility spectrometer only when an eluted gas condition to be analyzed is detected.
