Abstract
A first chromatogram is obtained by analyzing a second standard sample by size exclusion chromatography analysis using a first detector. Also, a second chromatogram is obtained by analyzing a solvent for the second standard sample by size exclusion chromatography analysis using the first detector. Then, from the difference between the first chromatogram and the second chromatogram, a third elution time in size exclusion chromatography analysis of the second standard sample using the first detector is determined.
