On the Temporal Stability of Analyte Recognition with an E-Nose Based on a Metal Oxide Sensor in Practical Applications

Ruslan ADİL AKAY TEGİN | Camilya SMANALİYEVA | Coşkan ILICALI

The paper deals with a functional instability of electronic nose (e-nose) units which significantly limits their real-life applications. Here we demonstrate how to approach this issue with example of an e-nose based on a metal oxide sensor array developed at the Karlsruhe Institute of Technology (Germany). We consider the instability of e-nose operation at different time scales ranging from minutes to many years. To test the e-nose we employ open-air and headspace sampling of analyte odors. The multivariate recognition algorithm to process the multisensor array signals is based on the linear d ...Более
