Scope

Main technical content: This document describes the method of determining niobium, tantalum, zirconium, and hafnium in samples using high-pressure confined-inductively coupled plasma mass spectrometry. This document is suitable for determining the content of niobium, tantalum, zirconium, and hafnium in soil and sediment samples. - Method detection limit: Niobium 0.02 μg/g, tantalum 0.02 μg/g, zirconium 0.03 μg/g, hafnium 0.02 μg/g. - Method determination range: Niobium 0.08~100 μg/g, tantalum 0.08~50 μg/g, zirconium 0.08~500 μg/g, hafnium 0.12~50 μg/g.
