There is a new method of BPA testing in tableware

"China Paint Online News Information"
tableware in the detection of BPA S has a new method, recently, Changzhou Inspection and Quarantine Bureau of Jiangsu Province, the dangerous package testing center came good news: the center uses advanced ultra-efficient liquid chromatography - series triple quad bar mass spectrometer, successfully developed bisphenol S detection technology, its detection low limit of up to 0.001mg/L, for enterprise products successfully out of the country paved the way for science and technology. The occurrence of BPA bottle incident has made consumers pay more and more attention to the importance of food contact material safety. In addition to BPA, which has been widely concerned, other alternative raw materials such as bisphenol S (4,4'-hydroxybiphenyl) and other substances have gradually become the new image of people's attention.
According to

, because bisphenol S has many excellent properties such as heat resistance, light resistance and antioxidant, can be used as a substitute for bisphenol A, for the synthesis of polycarbonate, epoxy resin, polyester, polyphenol resin, as well as polysacry, polyphenol ether; Studies have shown that BPA has a similar effect on the estrogen produced by BPA to bisphenol A, an endocrine interferon (environmental hormone) that is harmful to the reproductive system.
Japan and South Korea clearly stipulate that the amount of BPA in food simulations should not exceed 0.05mg/L, eu plastics regulations (EU) No.10/2011 and China's "Food containers, packaging materials additives use hygiene standards" (GB 9685-2008) have stipulated that the food simulation of BPA S migration limit of 0.05mg/kg. Due to the low limit, there is no domestic food simulation of BPA testing research reports, there is no corresponding testing methods or standards. Changzhou Inspection and Quarantine Bureau dangerous package testing center of the technical staff using advanced ultra-efficient liquid chromatography - series triple quad pole mass spectrometer, successfully developed the detection technology of BPA S, its detection low limit of up to 0.001mg/L.
