GB/T 39695-2020 Identification of volatile components in rubber flue gas using thermal desorption-gas chromatograph-Mass spectrometry. It details the collection method of rubber flue gas samples to ensure that the samples can reflect the true composition. Clarify the operation specifications and parameter settings of equipment such as thermal desorption instrument, gas chromatograph-Mass Spectrometry (MS). Rigorously describe the whole process from sample pretreatment to detection and analysis. According to this standard, volatile matter in rubber flue gas can be accurately identified, providing key data for evaluating the hazards of rubber production environment, developing environmental protection processes, and contributing to the green and sustainable development of the rubber industry.
