Scope

This document specifies the methods for determining the arsenic content in tungsten concentrate. It includes the atomic fluorescence spectrometry method (Method I) and the DDTCAg spectrophotometry method (Method II).
This document is applicable to the determination of arsenic content in tungsten concentrate. The determination range (mass fraction) of Method I is 0.0010% to 0.20%; the determination range (mass fraction) of Method II is 0.010% to 0.50%. For the overlapping part of the determination range, Method I shall be used as the arbitration method.
