Liquid chromatography packing material, liquid chromatography column and method for analyzing amine compound |
| abstract |
A liquid chromatography packing material which 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. |
