Abstract
In an analyzer, an oxidation reagent is supplied to an oxidation reaction portion, and after organic materials contained in the oxidation reagent are removed by oxidation decomposition, a sample is provided into the oxidation reaction portion to react with the oxidation reagent. An infrared gas analyzing portion starts detecting a peak for analyzing. Thus, even if a concentration of the component to be measured in the sample is low, the concentration can be measured accurately without being disturbed by a concentration of the impurities in the oxidation reagent.
