This standard specifies the method for the determination of arsenic content in tungsten powder, tungsten bar, tungsten carbide, tungstic acid and Miscellaneous tungsten compounds by hydride atomic absorption spectroscopy (AAS), which is applicable to the determination range of 0.00005% to 0.020%. After the sample is processed through a variety of chemical reaction analysis, the arsenic content is detected by AtomicAbsorption Spectroscopy. This standard provides a scientific basis for the analysis of arsenic content in tungsten products and is suitable for the field of material detection and quality control.
