Summary on Grant Application Form |
|
The PTR-MS offers rapid, very high sensitivity analysis of trace gases in air, and data on gas-phase proton transfer chemistry. Fundamental investigations, supported by our SIFT, of the reactions of H3O+,NH4+, and cluster ions with single VOCs will provide essential data for relating MH+ signals to the concentration of M. Experiments on 'real' air samples containing complex mixtures of VOCs will validate the performance of the PTR-MS for multicomponent analysis. Applications to detection and materials sciences, and to air pollution studies are proposed. The multidisciplinary research will be facilitated by the portability of the PTR-MS. DERA have a strong programme in detection science; the PTR-MS will probe the ion-molecule reactions that underlie the operation of the current generation of chemical agent monitors. Advances in air pollution studies depend on the selective detection of a variety of pollutants in a complex environment, a challenge to which the PTR-MS is ideally suited. We will confirm the capabilities, and carry out studies of the pollution resulting from car engine exhausts. Materials science applications will exploit the very high sensitivity of the PTR-MS, to support the development of new liquid crystal sensors, and to quantify the release of VOCs from polymer composites.
