See Chinese contents: GB/T 30902-2014 GB/T 30902-2014: Inorganic chemicals for industrial use -- Determination of impurity element -- Inductively coupled plasma optical emission spectrometry (ICP-OES)
This Standard specifies the principle, reagents, instruments, apparatuses, analysis steps, precision, and recovery rate for the determination of metallic and non-metallic impurity elements in inorganic chemicals for industrial use using inductively coupled plasma optical emission spectrometry (ICP-OES). This Standard applies to direct injection of liquid samples containing various impurities in inorganic chemicals for industrial use or test solutions after removing the matrix, using an inductively coupled plasma optical emission spectrometer for measurement.
