Commercial Metal Oxide Gas Sensors For Breath Analysis Sensitive to Higher Alkane Vapours

Within an ongoing European project on breath analysis by IOMS, sensitivity of sensors to various VOCs is studied, as breath VOCs are considered as lung cancer biomarkers. Sensitivities of several commercial metal oxide sensors to various VOC have been studied. It was found that two sensors reacted to decane presence. This is an unusual property for metal oxide gas sensors. This paper shows obtained results and details the methodology employed to obtain them.
