本文着重研究了低分子硅酸聚合体三甲基硅烷化产物在气相色谱中的定性和定量特性。通过与标准物对照及GLC-MS分析,确定了单聚、二聚、环四聚、链三聚在色谱中的保留值,用实验方法测定了单硅酯和二硅酯的氢火焰离子化检测器FID摩尔响应值,认为Garzó提出的无标样硅酯响应值的估计方法,存在一定的疑问,故重新提出和论证硅酯类物质的FID响应值应与其分子中三甲基硅基数成线性关系,并用实验数据和Garzó的实验数据作了分析和证实。
This article focuses on the qualitative and quantitative characterization of trimethylsilanated products of low molecular weight silicic acid polymers in gas chromatography. Through the comparison with standard and GLC-MS analysis, the retention of monomeric, dimeric, cyclometalated and trimerized chains in the chromatogram was determined. The flame ionization Detector FID molar response value, that Garzó proposed standard sample of silicone ester response value of the estimation method, there are some questions, it is re-proposed and demonstrated that the silicone ester FID response value should be the number of molecules with trimethylsilyl The linear relationship was analyzed and confirmed by experimental data and experimental data of Garzó.
