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.
