NERC/RSC CASE PhD Studentship, University of Birmingham Novel approaches to the measurement of atmospheric VOC mixtures using soft chemical-ionisation mass spectrometry - drift-tube techniques -School of Geography, Earth & Environmental Sciences -School of Physics & Astronomy, University of Birmingham -CASE Partner: Kore Technology Ltd. Natural and anthropogenic processes emit a wide variety of volatile organic compounds (VOCs) into the atmosphere. Many have different chemical properties, affecting their contribution to the production of ozone and secondary organic aerosol, and their toxicity. One approach to measure such species is mass spectrometry, for example PTR-MS (Proton Transfer Reaction Mass Spectrometry) may be used - however compound identification using MS approaches is challenging, as is not always clear which compounds are contributing to a given mass-charge ratio (m/z): many VOCs may be isobaric – i.e. have the same whole-number molecular mass (or are isomeric, with identical molecular masses), and may fragment. The aim of this project is to develop a new approach to distinguish between isobaric / isomeric atmospheric VOCs, using the PTR-MS approach. The project will involve laboratory development work in Birmingham and at our industrial partner, Kore Technologies Ltd, followed by trial / demonstration field measurements of atmospheric compounds, to demonstrate the viability of the method for identification of species such as aromatic and biogenic VOCs, building upon our successful proof-of-concept work. The project will provide a comprehensive interdisciplinary training in analytical science and mass spectrometric / molecular physics techniques, and in atmospheric composition and chemistry. Through the industrial CASE partner, Kore Technologies Ltd, the project will also provide exposure to a fast-moving commercial R&D environment to complement the academic training. Applications are invited from candidates who have, or expect to obtain, a good honours degree in a relevant subject (e.g. Chemistry, Physics, Environmental Science, Engineering).
