Scope

This Standard specifies the principle, reagents, instruments, equipment, analytical
procedures, precision and recovery rate for the determination of metallic and non-
metallic impurity elements in inorganic chemical products by inductively coupled
plasma mass spectrometry (ICP-MS).
This Standard is applicable to liquid samples containing multiple metal and non-metal
impurity elements in inorganic chemical products or direct sampling after removing the
matrix. Determination is carried out using inductively coupled plasma mass
spectrometry (ICP-MS).
