For the development of gas sensors applied to organic gas detection, the preparation of sample gases containing organic vapors with controlled concentrations is sometime necessary in accurately evaluating the gas sensor properties. In this study, using a diffusion method where liquid samples were heated and vaporized under a carrier gas flow, we prepared standard sample gases containing 2,6-diisopropylphenol (propofol), which are breath markers for diabetes and anesthesia depth, respectively. We used a NASICON (Na3Zr2Si2PO12; Na+ conductor)- based CO2 sensor combined with a Pt/Al2O3 combustion catalyst to prepare propofol gases with known concentrations. We demonstrated that the prepared propofol gases with constant concentrations were effectively detected by Au loaded-TiO2 nanotube sensors.
