应用：进口环氧树脂涂料中环氧丙烷及环氧氯丙烷单体的测定 顶空-气相色谱法
本标准规定了进口环氧树脂涂料中环氧丙烷及环氧氯丙烷单体含量的顶空-气相色谱检测方法。 本标准适用于环氧树脂涂料中环氧丙烷及环氧氯丙烷单体的测定。


浩瀚色谱（山东）应用技术开发有限公司建立了顶空-气相色谱法测定环氧树脂涂料中环氧氯丙烷单体残留量的方法。结果表明,环氧氯丙烷含量在2.5~500μg范围内,线性方程为y=0.207 7x+0.348 2,相关系数为r=0.999 5;方法检出限为5 mg/kg;平均回收率为91.0%~98.1%;相对标准偏差(n=6)为1.3%~3.0%。该方法简便、快速,重复性好,可用于环氧树脂涂料中残留环氧氯丙烷单体的快速分析。





Determination of propylene oxide and epichlorohydrin monomers in imported epoxy resin coatings
Determination of propylene oxide and epichlorohydrin monomers in imported epoxy resin coatings Detailed information:


Name: capillary column

Stationary Phase: Polyethylene Glycol

Specifications: 30m*0.32mm*0.5um

Model: HH-INNOWAX

Application: Determination of propylene oxide and epichlorohydrin monomers in imported epoxy resin coatings by headspace-gas chromatography
This standard specifies the headspace-gas chromatography detection method for the monomer content of propylene oxide and epichlorohydrin in imported epoxy resin coatings. This standard applies to the determination of propylene oxide and epichlorohydrin monomers in epoxy resin coatings.


Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has established a headspace-gas chromatography method for the determination of residual epichlorohydrin in epoxy resin coatings. The results show that the content of epichlorohydrin is in the range of 2.5~500μg, the linear equation is y=0.207 7x+0.348 2, the correlation coefficient is r=0.999 5; the detection limit of the method is 5 mg/kg; the average recovery rate is 91.0% ~98.1%; relative standard deviation (n=6) was 1.3%~3.0%. The method is simple, rapid and reproducible, and can be used for the rapid analysis of residual epichlorohydrin monomers in epoxy resin coatings.
