Sulfr hexafluoride gas handling - DILO

The key parameters here are the SF 6 purity (%), the moisture content and the concentration of decomposition products. In general, the gas quality must always be checked if a decision regarding the reuse of the SF 6 gas must be made or in the context of condition-based maintenance to prepare a trend analysis.

Ultra-Trace Analysis Technique for insulating gas Using Gas

As a result, GC-ECD is the most commonly used analytical system for tracer gas studies because of repeatable detection limits at parts per billion (ppb) concentration levels (3, 5–7, 9, 10). Although highly sensitive, GC-ECD is inherently limited because of its inability to actively identify compounds.
