GB/T 36488-2018 "Determination of Polycyclic Aromatic Hydrocarbons in Coatings" is a national recommended standard aimed at regulating the method for determining the content of polycyclic aromatic hydrocarbons in coatings and their films. The standard clearly stipulates that its core technical principle involves ultrasonic extraction of samples using solvents such as n-hexane, followed by separation, qualitative, and quantitative analysis using gas chromatography-mass spectrometry. According to the scope of application of the standard, this method is suitable for detecting various polycyclic aromatic hydrocarbons in coatings and films, and also provides reference value for the testing of raw materials used in coatings. Therefore, the core detection instrument required for implementing this standard is the gas chromatography-mass spectrometer. The establishment of this standard provides a unified and reliable technical basis for evaluating the environmental and safety performance of coating products.
