GB/T 6150.10-2023 《Methods for chemical analysis of tungsten concentrates—Part 10：Determination of lead content—Hydride generation atomic fluorescence spectrometry and flame atomic absorption spectrometry》 Related products

This standard specifies a method for the determination of lead content in tungsten concentrates. Applicable to the determination of lead content in tungsten concentrates, it includes two methods: hydride generation Atomic fluorescence spectrometry, AFS and flame atomic absorption spectroscopy (AAS) method. Method 1 is suitable for the determination of mass fraction in the range of 0.0010% to 0.30%, and Method 2 is suitable for the determination in the range of 0.10% to 0.50%. If the measurement ranges of the two methods overlap, Method 2 is used as the arbitration method.
