Scope
Main technical content: This document describes the method of determining the content of silver, tin, and boron in ecological geochemical samples using the direct reading method of deep hole electrode emission spectroscopy. This document is suitable for the determination of the content of silver, tin, and boron in ecological geochemical samples. The measurement range is: silver, 0.010 μg/g to 1.2 μg/g; tin, 0.20 μg/g to 70 μg/g; boron, 0.50 μg/g to 200 μg/g.
