Rapid detection method for expired gas through on-line enrichment gas chromatography

The invention discloses a rapid detection method for expired gas through an on-line enrichment gas chromatography. The method mainly comprises the steps that: a collector is selected by using the expired gas to collect alveolar gas in the expired gas; VOCs (Volatile Organic Compounds) in the alveolar gas are adsorbed by a preconcentrator; the preconcentrator is heated to enable the VOCs enriched on an adsorbent to be desorbed; the preconcentrator is blown back by carrier gas to enable the VOCs subjected to the heat desorption to enter a chromatographic separation column along with the carrier gas for separation; and component gases of the VOCs after the separation enter a microplasma detector along with the carrier gas. After component gas molecules of the VOCs enter a discharge chamber of the microplasma detector, the component gas molecules are excited by the existing high-energy metastable-state particles, then are jumped back to ground states, and send characteristic optical signals; the characteristic optical signals sent by the jumping of the component molecules of the VOCs are focused and coupled to an optical fiber by a lens; the characteristic optical signals are transmitted by the optical fiber to a spectrograph for detection; a computer processes and stores data; and the rapid detection on the VOCs in the expired gas is realized. With the adoption of the method, components of the expired gas can be monitored in real time and on line.
