(57) [Summary] [PROBLEMS] To provide good performance even when the particle size distribution is wide, that is, to have low loss in the classification operation and the like, to have good yield, and to have high separation performance and long column life equivalent to that of the classified product. Provide a filler. A filler for liquid chromatography comprising a crosslinked polymer, wherein the polymer has an average particle size of 0.5. A filler for liquid chromatography having a particle size distribution of 20 to 40% and a CV value of 20 to 40%. |
