Ultra-Trace Analysis Technique for sf6 gas Using Gas

GC paired with a negative ion chemical ionization mass spectrometer (NCI-MS) may provide an alternative analysis technique for SF 6 detection in terms of both high sensitivity and selectivity. This paper details a procedure and an experimental methodology for the ultra-trace level detection of SF 6 in air utilizing gas chromatography with negative ion chemical ionization mass spectrometry (GC-NCI-MS).

Description. 973-gaz sf6 gas analyzer used for simultaneous measurement of humidity, SF 6 purity and SO 2 concentration. Pure SF 6 is the standard filling within GIS, but over time gas compartments become contaminated with water vapor (H 2 O) through permeation and by desorption from internal materials. Whilst water vapor and SF 6 do not normally react with each other, in the presence of a high-energy discharge, hydrogen and oxygen disassociated from water vapor will react with the sulfur and
