GB/T 7131-1986
ActiveIdentification of polymers by pyrolytic gas chromatography
裂解气相色谱法鉴定聚合物
Application Summary AI generated
This standard specifies the method for identifying polymers by analyzing their thermal degradation products using gas chromatography. It is applied in the chemical and materials testing industries for quality control, failure analysis, and material verification of plastics, rubbers, and other polymeric substances. The method is particularly useful when traditional spectroscopic techniques are insufficient due to insolubility or complex formulations.
