MS ISO 6978-1:2008 Natural gas - determination of mercury - Part 1: Sampling of mercury by chemisorption on iodine (First Revision) (ISO 6978-1:2003, IDT)

This part of ISO 6978 specifies a method for the determination of total mercury content in natural gas using a sampling method at pressures up to 40 MPa by chemisorption on iodine-impregnated silica gel. This sampling method is suitable for the determination of mercury contents within the range of 0.1 µg/m3 to 5000 µg/m3 in natural gas. This method is applicable to sampled gas volumes containing less than 20 mg hydrogen sulfide (absolute content) and less than a total liquid hydrocarbon condensate of 10 g/m3 under the sampling conditions. The collected mercury is determined by measuring the absorbance or fluorescence of mercury vapour at 253,7 nm.
