  • Effects of ambient pressures, He and Sf6 on O2 and CO2

    The CO2 and O2 tnesions were determined in the air cells of 14-16 day old chicken eggs before and after transfer to a 21% O2 in He or SF6 atmosphere. In the former gas mixture the air-cell PCO2 (which reflects the arterialized blood PCO2) fell rapidly from 32 torr in air to 17 torr in He-O2 attaining a new steady state in 2-4 h.Cited by: 24

  • Experimental investigation of a low pressure capacitively

    When compared to TALIF measurements; actinometry showed excellent quantitative agreement in pure O2 plasma but did not predict the rapid rise of [O] with SF6 addition and grossly overestimated [O] in O2 plasma containing SF6. However, reasonable qualitative agreement was shown for mixtures in the range of 10 to 60% SF6.

    SF6 Characteristics • Clayton found no mortality in rats exposed to SF6 (176,000 ppm) for 18 hours • Troshikhin and Issakyan observed increased respiration in rats exposed to 80% SF6 and 20% O2. SF6 can be an asphyxiant in acute high exposure conditions However, these levels are so high it’s unlikely that humans will be exposed to these

  • Atmospheric SF6: Trends, Sources, and Prospects

    Sulfur hexafluoride (SF6) is the most potent greenhouse gas known. Its atmospheric concentration has increased by 2 orders of magnitude since industrial production started in 1953. Once released into the atmosphere, SF6 will only be removed exceedingly slowly due to its atmospheric lifetime of about 3200 yr. These features have brought SF6 into the climatic impact discussion aimed at reduction
