Zusammenfassung: | The invention provides a gas sensitive-chromatography multi-information fusion electronic nose instrument anytime on-site detection and analysis method. Component units comprise a gas sensitive sensorarray module, a capillary gas chromatographic column module, a gas automatic headspace sample injection module, a computer control and analysis module, a high-capacity headspace volatile gas generation module, an automatic sample injection lifting module and auxiliary gas sources. Within the gas sample injection period T=300-600 s, the measured gas sample injection flow and the accumulated sampleinjection amount of the gas sensitive sensor array module and the capillary gas chromatographic column module are unequal, the sample injection time is not synchronous, and sensing information selection and analysis time synchronization are achieved; one-time anytime on-site detection on a detected sample is carried out to obtain a 69-dimensional sensing sample containing a response peak value, peak appearing time and an |
