ABSTRACT:
A separating agent which comprises a polysaccharide derivative having an Mw/Mn (wherein Mw and Mn represent the weight-average molecular weight calculated as polystyrene and the number-average molecular weight calculated as polystyrene, respectively), which indicates the extent of molecular weight distribution, of 1 to 3.
When liquid chromatography is effected using this separating agent as a column packing, the base line is highly steady, various types of solvents can be used as the eluent, and low-molecular polysaccharide derivatives are not eluted.
