GB/T 15076.2-2019 《Methods for chemical analysis of tantalum and niobium—Part 2:Determination of niobium content in tantalum—Inductively coupled plasma atomic emission spectrometry and stratography gravimetry》 Related products

This standard specifies methods for the determination of niobium content in tantalum by Inductance coupled plasma atomic emission spectroscopy (AES) and chromatographic separation weighting. It is suitable for the determination of niobium content in tantalum and its compounds, and the determination range covers 0.0010% to 20.00%. The standard describes in detail Sample Handling, reagent preparation and determination steps, provides a scientific method for the analysis of niobium content in tantalum materials, and provides technical support for the quality control of tantalum and its compounds.
