Detection and molecular weight determination of organic vapors |
| abstract |
Composite films comprising an organic salt (or GUMBOS) such as l-n-butyl-2,3-dimethylimidazolium hexafluorophosphate and a polymer such as cellulose acetate are prepared. These films are useful in detecting vapors of volatile organic compounds, and in determining their molecular weights. A quartz crystal microbalance-based sensor was designed by depositing a thin film of this composite material on the gold electrode surface of a quartz crystal resonator. The sensor exhibited rapid response toward a variety of volatile organic compounds, and complete regeneration, high sensitivity, low detection limits, and wide dynamic ranges. The ratio of the change in frequency to the change in motional resistance is a concentration-independent quantity that is proportional to the molecular weight of the absorbed chemical species. These properties facilitate the easy identification and molecular weight determination of a broad range of organic vapors. |
