sulphur hexafluoride detection system For determining the quality

SMILES is the acronym for Simplified Molecular Input Line Entry Specification, a chemical notation system used to represent a molecular structure by a linear string of symbols. With standard SMILES, the name of a molecule is synonymous with its structure: it indirectly shows a two dimensional picture of the molecular structure.

    Abstract. A rapid headspace method for the simultaneous laboratory determination of intentionally introduced hydrologic tracers, sulfur hexafluoride (SF 6 ), trifluoromethyl sulfur pentafluoride (SF 5 CF 3 ), Halon 1211 (CF 2 ClBr), and other halocarbons in water and gases is described.

  • Sulfur hexafluoride detection by Radar resonance enhanced

    In order to obtain a well defined spectral signature, the sulfur hexafluoride molecules are first dissociated by a focused pulsed Nd:YAG laser to sulfur difluoride molecules, which are then ionized by a pulsed, frequency tunable, narrow linewidth laser emitting in the ultraviolet. At the wavelength 269.5 nm, a concentration of 10 % of sulfur hexafluoride has been detected and the spectral signature shows some overlap with a carbon dioxide resonant spectral line.

  • Electric Power Systems Partnership | Fluorinated Gas

    Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for SF6, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. Since the 1950’s, the U.S. electric power industry has used SF6in circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and customer load centers. Several factors affect SF6 emissions from electric power systems, such as the type and age of the SF6-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of SF6, while modern breakers usually contain less than 100 pounds) and the handling and maintenance procedures practiced by electric utilities. Because of its long life span and high global warming potential (GWP), even a relatively small amount of SF6can impact the climate. The electric power industry uses roughly 80 percent of all SF6 produced worldwide. Ideally, none of this gas would b...
