Scope

Main technical content: This document describes the method of determining boron, chromium, tin, and tellurium in rock samples using high-pressure closed-inductively coupled plasma mass spectrometry. This document is applicable to the determination of boron, chromium, tin, and tellurium in rock samples. — The detection limits of the method are: B 0.41 mg/kg, Cr 0.020 mg/kg, Sn 0.002 mg/kg, Te 0.003 mg/kg. — The measurement range is: B 1.6 mg/kg to 1,000 mg/kg, Cr 0.09 mg/kg to 1,000 mg/kg, Sn 0.01 mg/kg to 100 mg/kg, Te 0.01 mg/kg to 100 mg/kg.
