GB/T 4324.3-2012 《Methods for chemical analysis of tungsten - Part 3: Determination of tin content - Hydrogenate atomic absorption spectrometry》 Related products

This standard specifies the method for the determination of tin content in tungsten powder, tungsten bar, tungsten carbide and other materials by hydride atomic absorption spectroscopy (AAS), which is suitable for the tin content in the range of 0.00005% to 0.020%. After the sample is analyzed, the tin content is determined by flow injection and hydride generator. This method is suitable for the analysis and quality control of trace tin in tungsten and its compounds.
