Abstract

See full text

An apparatus and a method for quantitative detection of gases are provided. The apparatus for quantitative detection of gases includes: a cavity ring-down spectroscopy device configured to quantitatively detect any characteristic gas in gases to be detected; a sample processing device disposed in a downstream of the cavity ring-down spectroscopy device and connected to the cavity ring-down spectroscopy device; and a mass spectrometry device disposed in a downstream of the sample processing device and configured to detect all the gases to be detected. Quantitative analysis of any variety of gases may be achieved without using standard gas in the technical solution proposed by the present application. Since no standard gas is required, the technology has significantly increased flexibility, and can be used for routine laboratory testing, for online analysis at industrial sites, as well as detection and analysis in environmental protection, national defense, aviation, aerospace, military and other fields.
