阳离子醚化剂中残留环氧氯丙烷检测
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses chloroform to extract epichlorohydrin in the etherifying agent, and uses isooctane as the internal standard to analyze the trace organic impurity epichlorohydrin in the etherifying agent by gas chromatography Propane content. The method is fast and convenient, and a single sample test can be completed within 1 hour. The results show that the linear range of the method is 1-30 mg/kg, the correlation coefficient R2 is 0.99987, the detection limit is 2 mg/kg, and the recovery rate of standard addition can reach 95.4%-101.9%. Meet the quality control of raw materials.
