Summary on Grant Application Form |

Gas chromatography-chemical ionisation mass spectrometry (GC-CIMS) offers an extremely high sensitivity method for the analysis of volatile and semivolatile organic compounds. Whilst automation technology for the handling of liquid samples is readily available, preparation of gas phase samples is much less developed. A lack of reliable non-cryogenic preconcentration technology has been an important limiting factor in determining the extent to which highly sensitive and selective GC-MS methods may be applied in areas such as at-plant process analysis and background environmental monitoring. This project aims to develop fully transferable analytical methods for automated ultra trace gas analysis using GC-CIMS. The project will focus in particular on addressing problems encountered in the remote long-term measurement of trace short-lived halocarbon gases in the astmosphere. Cascade Peltier-effect technology will be developed to enable essential gas preconcentration on supported adsorbent beds, with automated thermal desorption, separation and mass spectrometric detection. Sampling handling protocols for the removal of interferences such as water will be developed along with full QA/QC procedures and instrument control via telemetry. The use of stable gas standards suitable for long-term will also be investigated. The ultimate goal of the project os to develop instrumental methods for the selective detection of organic analytes in the gas phase at sub ppt concentrations, operating with full autonomy for perods of at least one month duration.
