【摘要】 <正> 化学键合固定相是高效液体柱色谱技术发展的重大成就。虽然历史很短,但已引起了人们的注意。由于（ω-三甲硅氧基）-烷基-三氯代硅烷,Cl₃-Si-（CH₂）_n-O-Si-（CH₃）₃分子中含有潜在的羟基,该类化合物又具有-Si-Cl活性基团,因此曾有人用它们处理薄壳型硅胶（Corasil Ⅱ）和无定形全多孔型硅胶（Merckosorb SI60）改性。在本实验中,我们选用堆积硅球为担体,试制了碳链长度不同的ω-羟基烷基堆积硅球用作高效液体柱色谱的更多还原

【Abstract】 A kind of chemically bonded silica-ω-hydroxyl alkyl silica is syrithe sized. The chemical identity and properties of the packing thus prepared are definitely confirmed with a series of elemental analysis, IR spectra, and thermal analysis etc. This HPLC column packings are tested for separation of sortie kinds of chemicals. The experimental results demonstrate that ω-hydroxyl alkyl silica can be used to separate some contpounds whether in normal-phase or in reverse-phase chromatography.更多还原
