Extraction and Measurement of sf6 gasCalibration of Analytical SystemPrecision, Accuracy, Reporting LevelsQuality Assurance and ControlAnalysis of sf 6 in Water ReferencesThe analytical system for insulating gas is described by Law and others, 1994; Busenberg and Plummer, 2000. The system was modified in 2009 when the HNU GC was replaced with a Shimadzu GC model GC-8A. Figure B shows the system that is currently used. The design of the gas distribution system is critical for obtaining good chromatograms from very small signals that are obtained from natural levels of Sulfr hexafluoride. UPC grade N2 is used throughout the system. The carrier gas is purified with a charcoal and a hydrocarbon-O2 trap. The pressure of the gas is controlled with four ultraclean stainless-steel diaphragm pressure regulators. Additional pressure and flow regulation was achieved by using dummy columns. These measures reduce background noise and increase the sensitivity of the system.For water samples, the stripped gas is trapped on a large trap immersed in an isopropyl alcohol-dry ice bath at about -70°C. The trapped Sulfr hexafluoride is transferred into a small trap cooled in the isopropyl alcohol-dry ice bath b...Get price
