摘要
以HP-5毛细管柱为色谱柱,醋酸戊酯为内标物,采用氢火焰离子化检测器(FID),定量测定正硅酸乙酯含量。峰面积与浓度呈良好的线性关系,r=0.9999,精密度良好,回收率99.1%～101.2%。
Objective： To establish a method for the determination of tetraethyl orthosilicate with cap- illary column gas chromatography. Methods： Selecting amyl acetate as an internal standard, using HP-5 cap- illary column gas chromatography with FID detector to determine tetraethyl orthosilieate. Results： A better linear relation was found between the peak area and the concentration of tetraethyl orthosilicate, r = O. 9999, the precision was well, the recovery was 99.1%- 101.2%. Conclusion： This method for the determination of tetraethyl orthosilicate was simple, accurate and rapid.
