1. An analysis method including:
analyzing a reference sample that contains a predetermined amount of a predetermined component by an analysis device using a chromatograph and obtaining a reference detection value which is a detection value of the predetermined amount of the predetermined component detected by the analysis device;
calculating a judgment reference value which is a criterion for judging whether a concentration of a detection subject component in a measurement subject sample is equal to or larger than a reference concentration or equal to or smaller than the reference concentration based on a ratio of the reference concentration to the predetermined amount of the predetermined component in the reference sample and the reference detection value; and
analyzing the measurement subject sample by the analysis device and judging that the detection subject component with the concentration equal to or larger than the reference concentration has been detected in a case where a detection value exceeding the judgment reference value is detected in a peak detection time zone corresponding to the detection subject component.
