China Education Equipment Procurement Network News: According to the announcement issued by the General Administration of Quality Supervision, Inspection and Quarantine, from June 1, 2011, the production of baby bottles will be monitored, and the production of bottles containing bisphenol A will be prohibited. This website recommends solutions for the determination of bisphenol A (BPA) content and migration from related content published by Shimadzu Corporation.
The details are as follows:
Bisphenol A (BPA) is one of the most widely used industrial compounds in the world, mainly used in the production of various polymer materials such as polycarbonate, epoxy resin, polysulfone resin, polyphenylene ether resin, unsaturated polyester resin, etc. . In the manufacturing process of plastic products, the addition of bisphenol A can make it colorless and transparent, durable, lightweight and outstanding impact resistance, especially to prevent acidic vegetables and fruits from eroding the metal container from the inside, so it is widely used in canning In the process of manufacturing food and beverage packaging, milk bottles, water bottles and hundreds of other daily necessities. It can be said that BPA is everywhere.
The world produces 27 million tons of BPA-containing plastics every year. BPA can cause endocrine disorders and threaten the health of fetuses and children. Obesity caused by cancer and metabolic disorders is also considered to be related to this. Very low doses of bisphenol A can also have an impact on health, especially for fetuses and newborns, whose "exogenous effects" may cause harm through mutations. Therefore, the safety issue of bisphenol A has become the focus of public attention.
The EU banned the production of baby bottles containing the chemical substance bisphenol A (BPA) from March 2, 2011. From June 1, 2011, China banned the production of polycarbonate baby bottles and other baby bottles containing bisphenol A; from September 1, 2011, the import and sale of polycarbonate baby bottles and other Baby bottles containing bisphenol A are recalled by the manufacturer or importer. With the announcement of relevant national policies and regulations and the announcement of the Ministry of Health of China, industries involving bisphenol A will carry out comprehensive testing services, especially commodity inspection, quality inspection, CDC, etc. and production enterprises will increase inspection efforts.
Recently, Shimadzu Corporation, which has long paid attention to product safety and is committed to ensuring product safety with comprehensive and advanced testing and comprehensive solutions, has launched the LCMS method to measure the total content of BPA in consumer products and the migration of BPA in children ’s drinking utensils, tableware and feeding utensils solution. Shimadzu LCMS-2020 was used to analyze the total content of BPA in consumer products and the migration of BPA in children's drinking utensils, tableware and feeding utensils. The results showed that the standard curve of bisphenol A in the concentration range of 0.01 ~ 0.5 mg / L was linear and the correlation coefficient was 0.9999; the total content of BPA in consumer products and the detection limit of BPA migration in children's drinking utensils, tableware and feeding utensils The average recovery rates of the three spiked concentrations of 1.0 mg / kg and 0.01 mg / kg, 0.02, 0.05, and 0.1 mg / L were 93% and 92%, respectively, and the method had good reproducibility.

Shimadzu LCMS-2020 uses a uniquely designed ion source and ion optical system, with ultra-fast scanning, high-speed positive and negative polarity switching function, to achieve high sensitivity and high stability. Operation and maintenance are simple and convenient. It also has a unique multi-sequence measurement method, which can measure data under a variety of analysis conditions in one injection, which greatly improves the analysis efficiency. In addition to LCMS-2020, Shimadzu's LC-20A and LCMS-8030 can be used to analyze the bisphenol A project.
