Gas analysis information


Gas analysis may refer to:

  • Blood gas analysis, a method that measures arterial oxygen tension, carbon dioxide tension, and other aspects of a blood sample
  • Breath gas analysis, a non-invasive method that measures volatile organic compounds present in the exhaled breath
  • Dissolved gas analysis, a method that measures dissolved gases in insulating fluids
  • Evolved gas analysis, a method that measures the gas evolved from a heated sample that undergoes decomposition or desorption
  • Breathing gas analysis, especially for breathing gas mixtures
  • Trace gas analysis, as an application of mass spectrometry, ion-mobility spectrometry or a combination of the two methods

Gas analyzer may refer to:

  • Infrared gas analyzer
  • Residual gas analyzer
  • Orsat gas analyser
  • Thermal and Evolved Gas Analyzer, a scientific instrument aboard the Phoenix spacecraft
  • Helium analyzer, an instrument to measure the concentration of helium in a gas mixture
  • Electro-galvanic oxygen sensor, an device which consumes a fuel to produce an electrical output by a chemical reaction
