GB/T 9738-2008
ActiveChemical reagent - General method for the determination of water insoluble matter
化学试剂 水不溶物测定通用方法
Application Summary AI generated
This standard specifies a general gravimetric method for determining the amount of water-insoluble residue in chemical reagents. It is applied in analytical chemistry laboratories and chemical manufacturing quality control to assess the purity of solid or liquid reagents by filtering, drying, and weighing the insoluble fraction. The method is used across industries such as pharmaceuticals, fine chemicals, and research institutions to ensure reagent consistency and compliance with purity specifications.
