Jiangsu Changzhou inspection and quarantine bureau successfully developed epichlorohydrin detection technology
recently, Jiangsu Changzhou inspection and Quarantine Bureau dangerous package inspection this experimental machine adopts microcomputer for data processing and analysis, and the technicians of the testing center use advanced high-precision 1 Insert the sample into the stripping fixture and close the instrument gc/ms/ms, and successfully develop the detection technology of epichlorohydrin. Its detection limit can reach 0.1mg/l, which can fully meet the detection needs of relevant enterprises, help them control product quality, deal with foreign technical barriers, and ensure the smooth export of products
epichlorohydrin (also known as epichlorohydrin) is an important organic chemical raw material and fine chemical product, which is widely used in the future. The epoxy resin made from it has the characteristics of strong adhesion, chemical medium corrosion resistance, good chemical stability, high impact strength and excellent dielectric electrical properties. It is widely used in the industries of coatings, adhesives, reinforcing materials and food contact materials. Epichlorohydrin is a harmful substance with strong toxicity. Its vapor has strong irritation to eyes and respiratory tract. Repeated and long-term inhalation can cause lung, liver and kidney damage; Direct skin contact with liquid can cause burns. If inhaled in high concentration, it will also lead to inhibition of the central nervous system and even death
in view of the health hazards of epichlorohydrin, many countries have strict regulations on the content and migration amount of epichlorohydrin in food contact materials. The regulations on food contact materials in Japan and South Korea clearly stipulate that the migration amount of epichlorohydrin in food simulants shall not exceed 0.5mg/l, and the European Union plastics regulation (EU) no.10/2011 stipulates that the residual amount of epichlorohydrin in related finished products shall not exceed 1mg/kg. The new technology developed by Changzhou bureau this time will accurately detect the limit to 0.1mg/l, which effectively solves the worries of enterprises
