Inorganic chemicals for industrical usePreparations of standard and reagent solutions for chemical analysisPart 2: Preparations of standard solutions for impurity
1 Scope
This part specifies the methods of preparing standard solutions for impurity for chemical analysis of inorganic chemicals for industrial use.
It applies to the preparation of standard solution containing exact amount of certain element, ion or molecule in certain volume required for the determination of impurities in analysis of inorganic chemicals for industrial use. It may also be used for chemical analysis of other chemical products for industrial use.
