环氧丙烷是一种重要的有机化工原料,它不仅可以生产聚醚多元醇,进而生产聚氨酯,也可以生产用途广泛的丙二醇,除此之外,还可以生产非离子型表面活性剂,油田破乳剂,阻燃剂,农药乳化剂.环氧丙烷含量的测定给生产一定的指导意义.

　　浩瀚色谱,采用气相色谱归一化法,此方法操作简单,只要求出校正因子即可求环氧丙烷含量的测定.

　　浩瀚色谱（山东）应用技术开发有限公司用气相色谱法分析环氧丙烷中的微量杂质,以二乙烯基苯--乙二醇--二JIA基丙烯酸为色谱固定相,使各组份达到分离,并选择环庚烷或苯为内标物,提供了各杂质组份的重量相对响应值。准确度及精密度的相对误差及相对偏差均小于5%。

　　Epoxide propane is an important organic chemical raw material, which can not only produce polyether polyols and polyurethane, but also produce widely used propylene glycol. In addition, it can also produce non-ionic surfactants, oilfield demulsifiers, flame retardants, pesticide emulsifiers. The determination of epoxy propane content provides certain guidance for production

　　Vast chromatography uses gas chromatography normalization method, which is simple to operate and can determine the content of epichlorohydrin by calculating the correction factor

　　Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used gas chromatography to analyze trace impurities in epoxy propane, using divinylbenzene ethylene glycol diJIA based acrylic acid as the chromatographic stationary phase to achieve separation of each component, and selected cyclohexane or benzene as the internal standard, providing the relative weight response values of each impurity component. The relative error and deviation of accuracy and precision are both less than 5%.
