The objective of the present invention is to provide a more accurate method and system for analyzing a sample containing an optical isomer. This method is characterized in that, with reference to results of chromatography, fractions for which complete separation from one or a plurality of chromatograph peaks corresponding to one or a plurality of other components has been achieved, from the time at which the peak starts to rise from the baseline until the peak has completely returned to the baseline, are successively fractionated separately, and if complete separation cannot be achieved for a single component, the fractionated fraction is subjected to additional chromatography, and if complete separation is achieved, the fractionated fraction is subjected to chiral chromatography. |
