GB/T 38385-2019 "Determination of Disperse Yellow 23 and Disperse Orange 149 in Dye Products" is applicable to various dosage forms of dye products, specifying relevant determination methods. The sample is treated with a suitable extraction solvent, and after corresponding separation and purification steps, detection is performed using gas chromatography-mass spectrometry or high-performance liquid chromatography. Qualitative analysis is based on retention time, while quantitative analysis uses the external standard method. The standard clearly defines the sample pretreatment process, chromatographic conditions, and requirements for result calculation, providing a unified basis for quality control of these two specific dyes in dye products.
