Abstract

Abstract: A new silica gel bonded phase, dihydroxy triethylene glycol bonded stationary phase (DHG-BSP), was synthesized. The conditions for preparation, together with its physicochemical properties and applications were studied. It is shown that the DHGBSP is an excellent material with high concentration of bonded phase(394μmol/g), good thermal and chemical stabilities and highly selective separation for aromatic amines and some amino acids.

Key words: Dihydroxy chemical-bonded phase, Diethylene glycol, Stability
