  • A rapid method for the measurement of sulfur

    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. The high sensitivity of the procedure allows forCited by: 17

  • Measurement of functional residual capacity by sulfur

    Measurement of functional residual capacity (FRC) by the open-circuit multiple breath tracer gas washout technique is an established method. A system based upon washout of sulfur hexafluoride (SF6) during mechanical ventilation is described. The central unit in the system is a sensitive and rapid-response infrared SF6 analyzer.

  • Types of Circuit Breakers, Advantages, Disadvantages

    Sulphur Hexafluoride Circuit Breaker. The sulfur hexafluoride circuit breaker uses SF6 gas for extinguishing the arc. The SF6 gas has great arc extinguishing property, and it is also superior as compared to other arc quenching media such as oil or air. Advantages. Switching is very softer than, for example, vacuum breakers. Spikes in voltages

  • Ultrasound velocities for axial eye length measurement

    Since 1974, I have used individual sound velocities for each eye condition encountered for axial length measurement. The calculation results in 1,555 M/sec for the average phakic eye. A slower speed of 1,549 M/sec was found for an extremely long (30 mm) eye and a higher speed of 1,561 M/sec was note
