Abstract
To certify gas mixtures in the range of low (10 -3 -10 -8 g/m 3 ) mercury concentrations, we have proposed and tested a traceable method for measuring the mass concentration of mercury in gaseous media by inductively coupled plasma mass spectrometry (ICP/MS). The proposed method is based on a scheme that provides for the mass spectrometer calibration for saturated vapors (physical constant) of pure metallic mercury, dosed directly into the carrier gas stream - argon. The undoubted advantage of this method is its applicability to various gases and gas mixtures, which allows you to simulate any matrix medium that affects the measurement results of mercury content ...
