摘要

The development of new analytical methods for the detection of volatile organic compounds (VOCs) requires the preparation of standard gases at various concentrations. In this study, using a diffusion method where liquid samples were heated and vaporized under a carrier gas flow, we prepared standard organic gases containing acetone or 2,6-diisopropylphenol (propofol), which are breath markers for diabetes and anesthesia depth, respectively. A Pt/Al2O3 combustion catalyst was used in conjunction with a NASICON (Na3Zr2Si2PO12; Na+ conductor)-based CO2 sensor for the continuous determination of organic concentrations in the sample gas streams; the catalyst allowed for conversion of ppm concentrations of acetone or propofol to CO2. The results demonstrate that the present system is feasible for the preparation and concentration determination of standard VOC gases...
