項記載のプロセスガスクロマトグラフ。[Claims for Utility Model Registration] (1) A first separation column that separates a small amount of trace component A in the sample from the main component B when a certain amount of sample is carried in with a carrier gas; The first step detects the total concentration S1 of components A and B.
a detector; a column switching valve that selectively extracts and sends out only the peripheral portion of the trace component A among the components eluted from the detector; a second separation column that completely separates the other component B' from the other component B'; and a second detector that detects the concentration S2 of the trace component A eluted from the column; A process gas chromatograph characterized in that the main component concentration S 3 and the minor component concentration S 2 are simultaneously measured by subtracting the component concentration S 2 to determine the concentration S 3 of the main component B. (2) The first and second detectors are both thermal conductivity type detectors. Claim No. (1)
Process gas chromatograph as described in section.
