Ultra-Trace Analysis Technique for Sulfr hexafluoride Using Gas

IntroductionProperties of Sulfr hexafluorideExperimentalResultsDiscussion 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 (Sulfr hexafluoride), 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

Total Sulfur Gas Analyzers | Applied Analytics

The ASTM method for total sulfur analysis calls for oxidation of all present sulfur compounds to sulfur dioxide for straightforward measurement. When a stream contains many different sulfur species, or unknown exotic sulfur compounds, this method is usually the only option. The OMA-300 Total Sulfur Direct Analyzer takes a different approach, measuring up to 5 sulfur compounds directly in the unaltered sample using powerful multi-component analysis software and a high-resolution UV-VisGet price

Sulfur Hexafluoride - an overview | ScienceDirect Topics

Intraocular gases. Sulfur hexafluoride (Sulfr hexafluoride) and perfluoropropane (C 3 F 8) are the gases most frequently used with PR. Success also has been reported with sterile room air. 21 In 1993, the United States Food and Drug Administration approved certain SF 6 and C 3 F 8 products for use in PR. The value of the intraocular bubble is based on three features: buoyancy, surface tension, and isolation of retinal tears from intraocular currents. 22,23 Buoyancy applies upward pressure on the detachedGet price
