Abstract
The gas chromatograph system 10 has the gas chromatograph 1, and a detector 2. The detector 2 has the redox unit 14. The redox unit 14 has the reaction tube 142, the oxidation zone 146 and the reduction zone 147. The reduction zone 147 is disposed on the downstream side of the oxidation zone 146. The reduction zone 147 is disposed out of a position perpendicular direction above the oxidation zone 146. Hence, even if the air heated around the oxidation zone 146 moved upward by convection, the reduction zone 147 is prevented from being exposed to such hot air.
Claims8
A gas chromatograph system comprising:
- a column through which a sample component is introduced;
- a column oven that houses the column;
- and
- a detector that detects the sample component separated through the column,
- the detector comprising;
- a flow channel through which the sample component separated through the column passes;
- and
- a redox unit comprising an oxidation zone that oxidizes the sample component in the flow channel;
- and a reduction zone arranged on the downstream side of the oxidation zone in the flow channel, and reduces the sample component having been oxidized in the oxidation zone,
- wherein the redox unit is attached to the column oven with a positional relation that the reduction zone being arranged not perpendicularly above the oxidation zone.
