A Gas Chromatograph analyzes a gas or volatile liquid sample by separating components for detection. The discrete separation and positive identification of components and measurement of the composition with no interference is a positive advantage of the gas chromatograph. Making good use of this advantage, the process gas chromatograph is widely used in many industries.

Yokogawa manufactures two models of the GC1000 Process Gas Chromatograph: the GC1000 S/E/C(isothermal oven type) and the GC1000 D/T/W(programmed temperature type).

The GC1000 S/E/C can analyze gas and liquid samples from room temperature up to elevated temperatures corresponding to their boiling points. The GC 1000 D/T/W is capable of performing high resolution analysis by using capillary columns similar to laboratory gas chromatograph.
