Abstract
A gas component analyzing system having a diffusion scrubber and a chromatograph wherein a flow passage switch valve and a sample injection valve are switched to form a non-circulation flow passage for feeding an absorption liquid into the diffusion scrubber so that absorption liquid captures sample gas components until the sample gas components come into an equilibrium state. Then, both the above valves are switched to form a circulation flow passage for feeding the absorption liquid into a concentration column. Then, both the above valves are further switched to form the non-circulation flow passage to elute the sample gas components for subsequent detection thereof by the chromatograph.
