ABSTRACT:
In a liquid chromatographic system for analyzing biological or vital components in blood, etc., a separation column packed with a packing material of organic porous material containing carboxyalkyl groups as functional groups and having pore diameter of 600 to 1,200 .ANG. in dry state and an ion exchange capacity of 0.1 to 0.5 meq/g on dry basis is used to improve the chromatographic performance of the separation column, 5-component and 6-component analysis are carried out by switching separation columns of different column length or diameter, and judgement of column life is made by evaluation parameters.
