Fast pyrolysis RoHS detector

Industry background introduction:
RoHS is a regulation in the European Union that restricts the use of toxic and hazardous substances in electronic and electrical equipment (EEE). Its full name is the "Restriction of Hazardous Substances" directive. This directive is mainly used to standardize the material and process standards of electronic and electrical products, making them more conducive to human health and environmental protection. Initially, the directive established usage limits for six substances, including lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyls, and polybrominated diphenyl ethers, in electronic and electrical products. On June 4, 2015, the Official Journal of the European Union (OJ) issued the RoHS2.0 revised directive (EU) 2015/863, officially adding DEHP, BBP, DBP, and DIPP to the list of restricted substances.
After the issuance of this revised directive, EU member states are required to translate it into their own regulations and implement it by December 31, 2016. Starting from July 22, 2019, all electronic and electrical products exported to Europe (excluding medical and monitoring equipment) must meet this restriction requirement; Starting from July 22, 2021, medical equipment (including extracorporeal medical equipment) and monitoring equipment (including industrial monitoring equipment) will also be included in this control scope.
To detect the content of four phthalates in electronic and electrical products, the traditional chemical method involves steps such as sample crushing, extraction, impurity removal, concentration, and machine testing. In March 2017, the Py/TD-GC-MS method was approved by the International Electrotechnical Commission (IEC) as an approved method (the national standard has also been approved and is in a pending state). This method is used to analyze the phthalates restricted by the RoHS directive (IEC62321-8:2017) for the regulation of electronic and electrical products. Py/TD-GC, as a low configuration alternative to Py/TD-GC-MS, has been extensively tested and meets the screening requirements of enterprises for RoHS2.0 ortho benzene.
Compared to traditional chemical methods, using UPY-90Fast pyrolysis RoHS detectorThe Py/TD-GC method can quickly screen for phthalates in electronic and electrical products. This method does not require chemical pretreatment and eliminates organic solvents. The final test results can be obtained by directly weighing the sample and analyzing it on the machine. It is simple and fast, and is one of the effective detection methods for internal control in enterprises.
