LIQUID CHROMATOGRAPHY FILLER, LIQUID CHROMATOGRAPHY COLUMN AND METHOD FOR ANALYZING AMINE COMPOUND

摘要

The invention relates to a liquid chromatography packing material capable of more accurately and more easily analyzing an amine compound; a liquid chromatography column which is filled with the liquid chromatography packing material; and a method for analyzing an amine compound, which uses the liquid chromatography packing material. The liquid chromatography packing material according to the present invention includes a polymer packing material into which 1.50 mmol or more of carboxyl groups are introduced per 1 g of the packing material, and an index indicating pH of the surface of the polymer packing material as determined by hydrophilic interaction chromatography (HILIC) is 1.30 or more and the index indicating hydrophilicity of the surface of the polymer packing material as determined by a hydrophilic interaction chromatography (HILIC) is from 1.00 to 1.30.
