Gas chromatograph with dynamic response factors

Abstract

A gas chromatograph for analyzing content of a gas sample includes a sample gas inlet configured to receive the gas sample and a carrier gas source which provides a carrier gas. A separation column is configured such that individual component gases in the sample gas separate as they move through the separation column. A first sample valve is coupled to the sample gas inlet, the carrier gas source and to a sample loop which is configured to contain a sample volume of the gas sample. The first sample valve injects the sample volume into the separation column and individual component gases in the sample gas separate as they move through the separation column. A detector detects a concentration of an individual component gas as a function of a sensitivity of the detector. A controller changes a response factor of the gas chromatograph by changing at least one of the sensitivity of the detector and the sample volume.
