sulphur hexafluoride Analysis for testing

OSHA Compliance Officers should consult the OSHA Occupational Chemical Database prior to sampling, for current information regarding correct media and flow rates.. OSHA maintains a large number of methods, and in some instances a method may remain available for use, but with different sampling requirements than specified in a given method.

  • Ultra-Trace Analysis Technique for SF6 Using Gas

    Dec 01, 2014Abstract. Sulfur hexafluoride (SF 6) is widely used as a tracer gas because of its detectability at low concentrations.This attribute of SF 6 allows the quantification of both small-scale flows, such as leakage, and large-scale flows, such as atmospheric currents. SF 6 s high detection sensitivity also facilitates greater usage efficiency and lower operating cost for tracer deployments byCited by: 7

    The sensitivity of this method is enhanced if sulfur hexafluoride-doped hydrogen gas is used (Lioy and Waldman 1989). The advantages of using flame photometric detector analysis include low maintenance, high sensitivity, fast response, and no interference from nonsulfur species. However, this method is unable to discriminate between sulfur species.File Size: 256KB
