GB/T 4324.17-2012 《Methods for chemical analysis of tungsten - Part 17: Determination of sodium content - Flame atomic absorption spectrometry》 Related products
This standard specifies a method for the determination of sodium content in materials such as tungsten powder, tungsten bar, tungsten carbide, etc. by flame atomic absorption spectroscopy (AAS), suitable for sodium content in the range of 0.0003% to 0.080%. Absorbance of sodium is determined on AtomicAbsorption Spectroscopy after the sample has passed hydrogen peroxide and ammonia analysis. This standard ensures the accuracy and accuracy of the determination of sodium content in tungsten and its compounds, and is suitable for chemical analysis and quality control.
