Enhancing Selectivity and Detection in Miniaturised Analytical Separation Systems. 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.

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
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
Resolving dissolved organic matter: new multi-dimensional separation approaches. To fully understand and model global carbon cycles the source, nature and fate of oceanic dissolved organic carbon is an essential element. This project will develop, model and apply new orthogonol and complementary separation science based technologies to further the comprehensive characterisation and understanding of these complex systems.

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

Enantiomeric characterisation allows evaluation of drug purity for potentially harmful constituents, consumer protection against adulteration of essential oils and natural materials, and study of chemical interactions in biochemical/environmental systems. Chromatograph technologies (GC, HPLC and CE)for enantioseparation are available, however limitations prevent multicomponent characterisation of complete sample mixtures. Critical choices involve: choosing a chiral selector that interacts differentially upon all enantiomers; incorporation of selector into high-efficiency chromatographic systems; application to all target compounds in the sample. We will synthesise novel chiral selectors, incorporate these into new separation columns, apply ultra-high resolution 2-dimensional GCxGC to broad-spectrum chiral analysis of volatile chemical samples.Read moreRead less

Due to the way in which multiple processes are integrated in a micro Total Analysis System (µTAS), they offer substantial advantages over current technology, in terms of speed, cost of analysis, portability and operator simplicity and safety. This has considerable potential benefit for Australia, specifically for the remote and rural analysis of drugs and metabolites in biological fluids such as blood, serum, urine and saliva. These devices will have application for point-of-care testing in therapeutic drug monitoring, which will improve medical treatment and the patient's quality of life, as well as for on-site analysis in forensics for the rapid determination of illicit drugs and performance enhancing substances in our elite athletes.
