Abstract
An analysis method of performing an analysis on a sample containing a first substance and a second substance that has an influence on an analysis of the first substance in regard to a concentration of the first substance, includes performing an analysis on the sample in regard to the concentration of the first substance to obtain sample analysis data, and deriving a result of analysis in regard to a concentration of the first substance based on the sample analysis data and adjustment information that is set based on the influence.

An analysis method of performing an analysis on a sample containing a first substance and a second substance that has an influence on the analysis of the first substance, comprising:
- setting adjustment information based on a relationship between an area of a standard sample peak and an area of a reference sample peak, the standard sample peak is a mass analysis peak of a standard sample that contains the first substance at a known concentration and contains the second substance, and the reference sample peak is a mass analysis peak of a reference sample that contains the first substance at the known concentration and does not contain the second substance,
- setting an analysis peak threshold value based on the adjustment information,
- performing mass analysis on the sample to obtain sample analysis data including an area of a sample analysis peak;
- and
- determining a concentration of the first substance in the sample based on a comparison between the analysis peak threshold value and the area of the sample analysis peak, wherein the mass analysis is performed by a Pyrolysis Gas Chromatograph-Mass Spectrometer.
