title: Rapid temperature-programmed separation of carbon monoxide and carbon dioxide on a packed capillary column in gas chromatography: application to the evaluation of photocatalytic activity of TiO2.
abstract: Carbon monoxide (CO) and carbon dioxide (CO2) were determined in a conventional capillary gas chromatography-flame ionization detector (GC-FID) by introducing a packed-capillary column and a methanizer. Due to good compatibility with rapid temperature-programmed operation of the packed capillary column, several volatile compounds, including CO and CO2, were rapidly eluted along with satisfactory resolution and sample loading capacity. The limit of quantifications of CO and CO2 were 5 and 3 ppm, respectively, with an injection volume of 0.5 mL. The developed system was then successfully applied to evaluating the photocatalytic decomposition of volatile organic compounds on titanium dioxide (TiO2).
