GC322 - Compact Gas Chromatograph

Dual-detector capability

The GC 322 is a compact gas chromatograph designed for chromatographic separation. It enables you to analyse chemical compounds in both gas and liquid samples. It is a highly-reliable and robust compact gas chromatograph. Another major advantage of the GC322 is its flexibility: there are 5 optional detectors to choose from: PID, FID, TCD, FUVAD and FPD.

Measurement scale

sub ppb to% - depending on detector and options such as concentrator.
