GB/T 38608-2020 "Method for Determination of Volatile Organic Compounds (VOCs) Content in Inks" is applicable to the determination of VOCs content in various ink products and specifies two testing methods: the difference method and the gas chromatography method. The difference method calculates the VOCs content by measuring the mass difference of the ink sample before and after baking; the gas chromatography method uses capillary column separation and hydrogen flame ionization detection, with quantification performed by the external standard method. The standard clarifies the requirements for sample preparation, testing conditions, and result calculation, with different methods applicable to different types of inks, ensuring the accuracy and applicability of the test results.
