Abstract
Most of chemical gas sensors present cross-sensitivity towards humidity. In this study, we investigate the possibility to exploit water permeability of polymeric materials to develop a low-cost and scalable method for reducing the water content of gas samples for sensors analysis. Sampling bags should be disposable and thus minimize the risk of cross-contamination. A custom-made system for testing different polymeric materials has been implemented. Preliminary results prove the capability of some of the investigated materials to decrease the moisture content without losing VOC of interest for the purpose of the analysis.
