发展了一种用于制备反相高效液相色谱填料的实用、经济的方法。以γ环氧丙基氧丙基三甲氧基硅烷为中间偶联试剂,将十八烷基脂肪酸键合至硅胶上。元素分析、色谱测试验证了该工艺的可行性和填料的反相色谱行为。
A practical and economical method for preparing RP-HPLC packing has been developed. The octadecyl fatty acid was bonded to silica gel using γ-glycidoxypropyltrimethoxysilane as an intermediate coupling reagent. Elemental analysis and chromatographic testing confirmed the feasibility of the process and the reversed-phase chromatographic behavior of the packing material.
