Abstract
Provided are a method of quickly and simply confirming the success or failure of resolution of optical isomers with the use of a column for resolving optical isomers and a method of simply designing the conditions of the eluent composition under isocratic elution conditions. In resolving optical isomers, the success or failure of the resolution can be simply and quickly confirmed by employing an HPLC gradient elution analysis method with the use of a column for resolving optical isomers. When the resolution is successfully conducted, the eluent composition under isocratic elution conditions can be estimated from the elution time in the gradient elution analysis.
