    摘要: A system for certifying a concentration of gas in a cylinder includes a gas cell configured to receive a sample gas from a cylinder, and an FTIR module coupled to the gas cell for scanning the sample gas and forming a beam spectrum. A processor is coupled to the FTIR module for calculating an intensity response of the sample gas based on the beam spectrum. A storage device is included for storing data points of a plot of intensity response of a known gas versus concentration levels. The processor is configured to interpolate between the stored data points of the plot to determine an interpolated data point corresponding to the intensity response of the sample gas. The processor provides to the user a concentration level of the sample gas, based on the interpolated data point.

    摘要: A leak detection system for detecting a leak within a duplex valve assembly is disclosed. The duplex valve assembly includes a first valve, a second valve and an intermediate fluid flow passageway fluidly interconnecting the first valve to the second valve. The leak detection system includes a means for indicating whether the first valve is maintained in a closed position or an open position, a means for indicating whether the second valve is maintained in a closed position or an open position, and a pressure change detector within the intermediate fluid flow passageway. The pressure change sensing means is at least partially positioned within the intermediate fluid flow passageway for detecting a pressure change within the intermediate fluid flow passageway.
