标准范围
This document specifies a method for the determination of alkylmercury compounds in filtered water
samples by gas chromatography-mass spectrometry after phenylation and solvent extraction.
This method is applicable to determination of individual methylmercury (MeHg) and
ethylmercury (EtHg) compounds in surface water and waste water.
The method can be applied to samples containing 0,2 μg/l to 10 μg/l of each compound as mercury
mass. Depending on the matrix, the method may also be applicable to higher concentrations after
suitable dilution of the sample or reduction in sample size.
