YS/T 899-2013 Methods for chemical analysis of high purity tantalum—Determination of trace impurity element content—Glow discharge mass spectrometry
Abstract
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.
