GB/T 14352.20-2021 《Methods for chemical analysis of tungsten ores and molybdenum ores—Part 20:Determination of niobium, tantalum, zirconium, hafnium and 15 rare earth elements content—Inductively coupled plasma mass spectrometry》 Related products

This standard specifies methods for the determination of niobium, tantalum, zirconium, hafnium and 15 rare earth elements (such as yttrium, lanthanum, cerium, etc.) in tungsten and molybdenum ores by Inductance Coupled Plasma Mass Spectrometry (ICP-MS). Through melt analysis and mass spectrometry of samples, various rare earth elements can be accurately quantified, providing a standardized technical method for the analysis of rare elements in ores, suitable for mineral resource assessment and quality control in industrial applications.
