Miniaturisation-compatible stationary phases and detection techniques will be developed for microseparation techniques of capillary electrochromatography and chip-based separation systems, and their analytical applications will be investigated. Replaceable stationary phases (RSP) of chromatographic particles suspended in reversible gels will be created by delivering a liquid RSP to the column followed by in situ immobilisation. This approach offers flexibility in optimising a number of parameters of the column and of its use for sample pre-treatment and preconcentration. Pulsed potentiometric detection will be developed for the abovementioned microseparation techniques, combining the advantages of pulsed amperometric techniques with the more universally responding potentiometric detection.Read moreRead less
Rapid method development in pharmaceutical analysis using quality-by-design principles. Chemical analysis using separation methods underpins all stages of drug design and analysis. This project will generate new approaches to greatly reduce the time taken to develop a new method of analysis. This will be achieved through development of new computerised techniques for rapid screening, selection and optimisation of analytical methods.
Self-assembled nanolayers of functionalised latexes as selective and adaptable nano-stationary phases in separation science. A new approach is proposed for the design and synthesis of functionalised ion-exchange stationary phases for analytical nano-separation methods. Desired charged functional groups are first affixed chemically onto nanometre sized latex particles and these particles are then self-assembled mechanically as monoloayer coatings onto a suitable supporting template such as fused ....Self-assembled nanolayers of functionalised latexes as selective and adaptable nano-stationary phases in separation science. A new approach is proposed for the design and synthesis of functionalised ion-exchange stationary phases for analytical nano-separation methods. Desired charged functional groups are first affixed chemically onto nanometre sized latex particles and these particles are then self-assembled mechanically as monoloayer coatings onto a suitable supporting template such as fused silica, monolithic silica or polymer beds, microfibres or microtubes, and channels in microchips. The resultant coated surface then acts as a highly efficient ion-exchange stationary phase which will be used in a wide range of separation technologies including ion chromatography, capillary electrophoresis, capillary electrochromatography and solid-phase microextraction.Read moreRead less

Understanding of the behaviour of the nutrients controlling nuisance algae in water bodies is currently limited by the cost and logistics of collecting and analysing the large numbers of samples required.
This proposal describes the development and evaluation of portable multiparameter micro analysis systems that will be capable of high frequency measurements from a sampling vessel. This will enable environmental agencies to perform rapid on-site mapping of nutrients and other water quality parameters in large water bodies, intensive scale mapping of effluent mixing and dispersal zones, quick assessment of the impact of dredging and aquaculture, and compliance monitoring in effluent streams.

This project aims to develop a new generation of mechanically and thermally stable carbon-nanocarbon composite adsorbents for ultra-high-performance liquid chromatography. The structure of adsorbents will be constructed according to advanced core-shell design with non-porous carbon central core and porous shell formed by highly ordered uniform nanocarbon particles. The unique properties of carbon-nanocarbon composite adsorbents will put liquid chromatography to qualitatively new levels of the separation performance that may open new possibilities for medicine and biodiagnostics. The resulting technology also has a strong potential to be used in other priority areas such as preparation of electrodes and supercapacitors for energy storage devices.Read moreRead less
