GB/T 2381-2013 "Dyes and dye intermediates - Determination of content of insoluble matter" is applicable to the determination of insoluble matter content in dyes and dye intermediates. The test principle involves dissolving the sample in a specified solvent, filtering the insoluble matter through a sintered glass crucible, and then calculating the content of insoluble matter after drying and weighing. The detection requires the use of instruments such as an analytical balance, constant temperature drying oven, sintered glass crucible, and suction filtration device, with strict control over filtration and drying conditions, providing technical specifications for assessing dye purity and ensuring application performance.
