Stationary phase for chromatography

A stationary phase for chromatography, comprising inorganic carrier particles to which is bonded a polymer having a hydrophilic group on repeating units of a main chain thereof,

• wherein the stationary phase has a structure represented by Formula (II):
• wherein in Formula (II), W′ is a single bond or an alkylene group of 1 to 10 carbon atoms which may have a branched chain;
• W″ is hydrogen or an alkyl group of 1 to 12 carbon atoms;
• X is an amide group, an ester group, an N-alkylamide group of 1 to 3 carbon atoms, an ether group, a sulfoxide group, a sulfone group, a sulfide group, or a phosphate ester group;
