GB/T 37039-2018 is a national recommended standard for the determination of seven free-state harmful solvents in various dye products, aiming to provide a basis for the environmental protection and safety quality control of products. The standard stipulates that dichloromethane is typically used as the extraction agent during testing, and dye samples are subjected to ultrasonic extraction. Subsequently, gas chromatography-mass spectrometry (GC-MS) is primarily employed for the qualitative and quantitative analysis of the extraction solution. To ensure the precision of the method, the standard specifies clear requirements for instrumentation and operational procedures, and auxiliary equipment such as analytical balances is also involved during implementation.
