See Chinese contents: GB/T 30903-2014 GB/T 30903-2014: Inorganic chemicals for industrial use -- Determination of impurity element -- Inductively coupled plasma mass spectrometry (ICP-MS)
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).
