GB/T 4324.4-2012 《Methods for chemical analysis of tungsten - Part 4: Determination of antimony content - Hydrogenate atomic absorption spectrometry》 Related products

This standard specifies the method for the determination of antimony content in tungsten powder, tungsten bar, tungsten carbide and other materials by hydride atomic absorption spectroscopy (AAS), which is suitable for the antimony content in the range of 0.00005% to 0.020%. After the sample is analyzed, the antimony content is determined under certain conditions. This method is suitable for the analysis and detection of trace antimony in tungsten and its compounds, providing a reliable basis for material quality control.
