GB/T 42162-2022 uses thermal desorption (dynamic headspace) combined with Capillary gas chromatography to determine residual monomers and Miscellaneous volatile low molecular weight compounds in raw rubber. The standard details how to collect representative raw rubber samples, standardizes the operation of thermal desorption equipment and capillary tubing Gas Chromatograph, and strictly sets key parameters such as temperature and time. According to the process, various volatile matter in raw rubber can be accurately determined, providing a basis for rubber mass control and process optimization, and helping to produce better and safer Rubber.
