ISO 6978-2:2003

This standard was last reviewed and confirmed in 2019. Therefore this version remains current.

Abstract

This ISO 6978-2:2003 specifies a method for the determination of total mercury content of pipeline quality natural gas using a sampling method by amalgamation on gold/platinum (Au/Pt) alloy thread. This method is applicable to the sampling of raw natural gas when no condensation is present. At atmospheric pressure, this method is suitable for the determination of mercury content within the range of 0,01 microgram /m³ to 100 micrograms/m³ in natural gas samples. At higher pressures (up to 8 MPa), this sampling method is suitable for the determination of mercury contents within the range of 0,001 microgram/m³ to 1 microgram/m³. The collected mercury is determined by measuring the absorbance or fluorescence of mercury vapour at 253,7 nm.
