| titleOfInvention | Expiratory air on-line preconcentration gas chromatography method for quick |
| abstract | The invention discloses a kind of expiratory air on-line preconcentration gas chromatography method for quick, mainly comprise: utilize the alveolar gas in breath selection device collection expiratory air; Utilize the VOCs in preconcentrator absorption alveolar air; Heating preconcentrator makes enrichment VOCs desorption on the sorbent, sweeps VOCs that preconcentrator makes Thermal desorption get off enter chromatography column with carrier gas and be separated with carrier gas blowback; The VOCs component gas be isolated to enters microplasma detecting device with carrier gas.Excited by wherein existing high-octane metastable particle after above-mentioned VOCs component gas molecule enters microplasma detecting device arc chamber, transition is afterwards returned ground state and is sent characteristic light signal; Utilize lens that the characteristic light signal focus that each for VOCs component molecular transition sends is coupled to optical fiber, detected to spectrometer by Optical Fiber Transmission, and store data by computer process, realize the quick detection to VOCs in expiratory air.Adopt method of the present invention can the component of real time on-line monitoring expiratory air. |
