GB/T 36907-2018 "Determination of Aniline Compounds in Dye Products" is a quality and safety standard targeting specific harmful substances in dyes, aimed at regulating the detection of 19 types of aniline compounds. This standard is applicable to dye products in various formulations, providing a critical methodological basis for ensuring environmental friendliness and safety. According to relevant information, the detection method typically involves ultrasonic extraction of samples using organic solvents (such as dichloromethane) and qualitative and quantitative analysis using gas chromatography-mass spectrometry. Implementing this standard primarily requires core detection instruments such as gas chromatographs and mass spectrometers to achieve precise separation and determination of the target compounds.
