Gas chromatographic component analysis system and component detector including an oxidation-reduction furnace, reaction cell and photodetector

A component detector used along with a gas chromatograph having a separation column,

• the component detector comprising:
• an oxidation-reduction furnace that has a first flow path through which a gas including a sample component separated by the separation column flows, and oxidizes and reduces the sample component in the gas flowing through the first flow path;
• a reaction cell that has an inlet for the gas including the reduced sample component and generates a chemical reaction accompanied by emission of light with respect to the sample component introduced from the inlet;
• a photodetector that detects light generated in the reaction cell;
• and
• a detector casing that stores the oxidation-reduction furnace and the reaction cell, wherein a downstream end of the first flow path and the inlet of the reaction cell are connected via a second flow path, the oxidation-reduction furnace and the reaction cell are held by the detector casing, and
• the second flow path is provided outside of the detector casing and is attachable to and detachable from a downstream end of the oxidation-reduction furnace and the inlet of the reaction cell.
