  • Pressurized detectors substance analyzer
    Patent number: 8128874
    Abstract: A method to measure the concentration of a constituent element in a gas sample contained in an analyzer. A sample cell of a detector has an inlet and an outlet. The outlet of the sample cell is sealed. A predetermined mass of a gas sample is received through the inlet into the sample cell over a predetermined pressurization period until substantially the entire mass of the gas sample contained in the analyzer is contained within the sample cell. The gas sample is pressurized to a predetermined pressure over the pressurization period. A concentration of a constituent element in the pressurized gas sample is determined.
    Type: Grant

  • Pressurized detectors substance analyzer
    Publication number: 20080198381
    Abstract: An apparatus, system and method to measure the concentration of a constituent element in a gas sample contained in an analyzer. A sample cell has an inlet and an outlet. The inlet is to receive a predetermined mass of a gas sample and the outlet is to couple to a valve. The sample cell is to receive the predetermined mass of the gas sample over a predetermined pressurization period until substantially the entire mass of the gas sample contained in the analyzer is contained within the sample cell. The gas sample is pressurized to a predetermined pressure over the pressurization period. A detector cell is located adjacent to the sample cell. The detector cell is to determine a concentration of a constituent of the pressurized gas sample.
