Abstract

A gas chromatograph for connection to a source of carrier gas and a source of a sample gas. The gas chromatograph includes a first bridge circuit with a sample sensor connected therein and a second bridge circuit with a reference sensor connected therein. The outputs of the bridge circuits are digitized and then subtracted from each other in a processor.
