Materials of 3D structure for HPLC columns have been prepared. Silica spheres with high purity were first funetionalized with Substance A and a range of other substances, and finally followed by quaternization with iodomethane to form the final product. A standard solution of four certain phthalates was used to verify the chromatographic performance of the resulting packing materia1. Quantification analysis was performed by the external standard method. Linear relationships were found between the peak areas and the mass concentrations of the four certain phthalates in definite ranges, with detection limits (3S/N) of 5 mg·kg-1 and the low limits of determination (10S/N) of 10 mg·kg-1. Recovery rates obtained by standard addition method were in the range of 100.8~106.8% and RSDs (n=6) were less than 4%, which meeting the requirement of routine experiment.
