Zero gas definition

Zero gas means a gas containing no analyte, which is used to set a zero response on an analyser.
Zero gas means a gas, usually air or nitrogen, which is used as a reference for establishing or verifying the zero point of an exhaust gas analyzer.

Examples of Zero gas in a sentence

  • Zero gas was supplied to the manifold at ambient pressure, and the analyzer’s sample flow rate was measured with the bubble meter.

  • Zero gas stream corresponds to an air stream that is purified and compressed in the laboratory.

  • Zero gas was used for the test and the flow was adjusted using the needle valves before the Valco valve.

  • Zero gas response must be within ±0.2 percent of span (the CFR requires ± 0.3 percent).

  • Zero gas also was sampled dozens of times during the verification period by the Argus-Hg 1000.
