YS/T 229.4-2013 Chemical analysis methods for high purity lead.Part 4:Determination of trace impurity elements content.Glow discharge mass spectrometry (English Version)
This part of YS/T 229 specifies the method for determining the content of trace impurity elements in high-purity lead. The measured elements are shown in Table 1. This section is applicable to the determination of trace impurity element content in high-purity lead. The measurement range of each element is as follows: the measurement range of sulfur and selenium elements is 100 μg/kg~5 000 μg/kg, and the measurement range of other elements is 1 μg/kg~5 000 μg/kg.
