Scope

This standard specifies the determination method for the content of trace elements in high-purity tantalum, and the elements to be determined are listed in Table 1. This standard is applicable to the determination of trace element content in high-purity tantalum. For all elements except niobium, molybdenum, and tungsten, the determination range is 1 μg/kg to 5000 μg/kg, and for niobium, molybdenum, and tungsten, the determination range is 1 μg/kg to 100,000 μg/kg.
