Ultra-Trace Analysis Technique for gaz sf6 Using Gas

IntroductionProperties of gaz sf6ExperimentalResultsDiscussion and ConclusionsAcknowledgmentsA tracer gas, by definition, can be any substance that does not have a significant background presence in the region being investigated. Tracers must also be non-toxic, non-allergenic, chemically inert, odorless, tasteless, non-flammable, non-explosive, easily transported, easily dispersed, easily sampled, quantified with high reliability, measured with repeatability and economical to deploy (1, 2). Sulfur hexafluoride (sf 6), halogenated compounds and perfluorocarbons are examples of such substances, which are also, incidentally, the most commonly used tracer gases. Tracers have been applied in a large variety of study areas including commercial heating, ventilating and air conditioning, atmospheric transport, pollutant dispersion, geological reservoir monitoring and underground mine ventilation to both qualitatively and quantitatively characterize various types of suspended, turbulent flows such as atmospheric currents and air stream movements where traditional practices were impra...Get price
