摘要：In the present invention, there is disclosed a detection method of presence of gaseous mixture components by the employment of different photoluminescence sensor response of the sensor array individual measuring modules, the sensitive detection layer of which has its surface differently chemically or electrochemically modified. The invention is characterized by simultaneous monitoring time behavior of the photoluminescence response of all the detection modules and the measured difference in the photoluminescence intensity serves then for the determination of the concentration of the monitored components in the gaseous mixture. A suitable surface modification of the separate photoluminescence sensitive layers of the sensor array measuring modules causes a different interaction of the detected components in the gaseous mixture with a surface recognition layer of the sensor layer and thus the measured photoluminescence is changed. In case of suitable number of the sensor modules, it is possible to determine from the measured photoluminescence changes a quantitative representation of the monitored gaseous mixture components.
