Scope

Scope: This document defines the terms and definitions of ion-adsorption rare earth ores and describes the method of determining the total amount of ion-phase rare earths in ion-adsorption rare earth ores by inductively coupled plasma mass spectrometry (ICP-MS). This document is applicable to the determination of the total amount of ion-phase rare earths in ion-adsorption rare earth ores by ICP-MS. The detection limit of the method is 3.4 μg/g, and the measurement range is 12 μg/g to 8,000 μg/g.
