Abstract
A gas analysis system includes a first column, a second column, a merge portion connected to an outlet of the first column and an outlet of the second column, a detector that detects a gas component introduced from the merge portion, a switching valve arranged between the first column and the merge portion, and a controller. The controller performs delay processing of switching the switching valve between open and closed states so that timing of start of introduction of the gas component separated in the first column into the detector is delayed to be later than timing of completion of introduction of the gas component separated in the second column into the detector.
