Scope
Scope: This document specifies the method for determining alkyl mercury (methyl mercury, ethyl mercury) and inorganic divalent mercury in environmental water samples using online solid-phase extraction-liquid chromatography-inductively coupled plasma mass spectrometry. This document is applicable to the determination of alkyl mercury (methyl mercury, ethyl mercury) and inorganic divalent mercury in environmental water samples with a concentration range of 0.5 ng/L to 100 ng/L. The scope specified in this document has been validated through inter-laboratory trials. Laboratories may extend the measurement range by changing the sample volume. Once the measurement range has been expanded, the laboratory should confirm this through experimental verification.
