The HG/T 4963.2-2016 "Determination of Hazardous Substances in Coating Printed Colorants Products, Part 2: Determination of 4-Aminoazobenzene, Gas Chromatograph-Mass Spectrometry" standard describes in detail the method of detecting 4-Aminoazobenzene in Coating Printed Colorants products using gas chromatograph-Mass spectrometry (GC-MS). This method is suitable for Coating Printed Colorants products in various dosage forms. The standard refers to national standards, such as analytical laboratory water specifications and test methods, numerical revision rules and limit value representation and determination, etc., to ensure the accuracy and Reliability of the determination process. After cleavage of the samples, solvent extraction and GC-MS analysis were used to quantify by the characteristic ion Peak area External standard method to ensure accurate determination of 4-aminoazobenzene content in colorants products.
