原甲酸三乙酯的气相色谱分析

Analysis of Triethyl Orthoformate by Gas Chromatography

采用 TCD检测器 ,醋酸正戊酯为内标的气相色谱法测定了原甲酸三乙酯的含量。该法具有较宽的线性范围 ,最大标准偏差为 2 .7× 1 0 -3,变异系数不大于 0 .63%

A method is introduced for determination of triethyl orthoformate by gas chromatography with thermal conductivity detecter using n-pentyl acetate as internal standard. The method has a good linear relationship.The standard deviations and coefficients of variation are 2.7×10 -3 and 0.63%, respectively.
