本文着重研究了低分子硅酸聚合体三甲基硅烷化产物(即三甲基硅酯类物质)在气相色谱中的定量特性。由实验测定了单硅酯和二硅酯的氢离子火焰检测器FID摩尔响应值。经分析认为Garzó提出的无标样硅酯响应值的估计方法,存在一定的疑问,而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,并用本文实验数据和Garzó的实验数据进行分析和证实。 This article focuses on the quantitative properties of trimethylsilyls (ie trimethylsilyl esters) of low molecular weight silicic acid polymers in gas chromatography. The FID molar response of monosilicic ester and disilicate hydrogen ion flame detector was experimentally determined. It is considered that there is some doubt about the method of estimating the response value of non-standard silicon ester proposed by Garzó. However, it is necessary to re-present and prove that the FID response of the silicon ester should have a linear relationship with the number of trimethylsilyl groups in the molecule. Experimental data and Garzó’s experimental data were analyzed and confirmed.
