Silica gel 硅胶---气相色谱固定相

硅胶---气相色谱固定相
硅胶---气相色谱固定相 详细信息：

硅胶是一种氢键型的强极性固体吸附剂，其化学组成为SiO₂.nH₂O。品种有细孔硅胶、粗孔硅胶和多孔硅球等。

气相色谱使用较多的是粗孔硅胶，其孔径为80-100nm，比表面积近300m²/g。

硅胶可用于分析N2O、SO2、H2S，SF6、CF2Cl2以及C1-C4烷烃等物质

硅胶的分离能力主要取决于孔径大小和含水量。

Silicone - Gas chromatography stationary phase

Silicone - Gas Chromatography Stationary Phase Details:




Silicone is a strong polar solid adsorbent with hydrogen bonding, and its chemical composition is SiO2. nH2O. There are varieties such as fine pore silica gel, coarse pore silica gel, and porous silica balls.



Coarse porous silica gel is commonly used in gas chromatography, with a pore size of 80-100nm and a specific surface area of nearly 300m2/g.



Silicone can be used to analyze substances such as N2O, SO2, H2S, SF6, CF2Cl2, and C1-C4 alkanes



The separation ability of silica gel mainly depends on its pore size and water content.
