Abstract :
This work deals with the use of a selective membrane separation process, namely pervaporation, as an on-line enrichment technique during sampling for analysis by so called "electronic noses" based on metal oxide sensors. It is how below how pervaporation permits enhancing considerably the performance of these sensors, while maintaining the analysis time short and sampling handling automated.
