Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses 5% squalane for sampling; 2% potassium hydroxide/Chromosorb103 (80-100 mesh); A rapid method for determining the content of triethylamine in aqueous solution by headspace gas chromatography using a glass column Using headspace gas chromatography for detection and chromatographic peak area external standard method for quantification The mass concentration of triethylamine is linearly correlated with the chromatographic peak area within the range of 0.25-2.9 mg/L, with a correlation coefficient of 0.999 8. The detection limit of the method is 0.29 mg/L. The sample recovery rate is 98.87% -100.95%, and the relative standard deviation of the measurement results is 0.78% -1.94% (n=6). This method is simple to operate and suitable for rapid batch detection of triethylamine in aqueous solutions
