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

This proposal aims to understand the chemical and physical properties governing the transport of ions into and within advanced extracting polymeric materials, known as polymer inclusion membranes, under the influence of an applied voltage. These membranes are dry-to-touch and represent a new and potentially powerful analytical platform for environmental, medical and industry sample preparation. By understanding the transport mechanism, new membranes will be developed, capable of purifying and concentrating diverse targets chemicals from liquid and solid samples. These processes can take place during sample transportation to a centralised laboratory thus simplifying and streamlining analysis upon arrival to decrease drastically its costs.Read moreRead less

Current techniques for membrane protein are inadequate for the emerging proteomic challenge, in which approximately 40% of proteins are predicted to be membrane associated. The aim of this proposal is to develop a new approach to purify membrane proteins using our recently-developed immobilised membrane chromatography materials. The present proposal will provide a new high-resolution separation technique that allows isolation and on-line mass analysis of complex mixtures of membrane proteins for subsequent proteomic analysis, high-throughput screening or structural studies and could form the basis for further development of new commercial tools for membrane protein analysis.Read moreRead less
Integrated Multidimensional Gas Chromatography - Spectroscopic Detection Methodology for Chemical Marker Discovery. Chemical species are pervasive in our modern society and are found in personal care products, foods, additives, petroleum products, illicit drugs, pharmaceuticals and pollutants.

Chemical species are pervasive in our modern society and are found in personal care products, foods, additives, petroleum products, illicit drugs, pharmaceuticals and pollutants. Each sample must be analysed to determine its accurate composition, and as a safeguard. This requires chemical methods of analysis. Classical chemical methods may fail when samples become too complex, or they may lead to imprecise identification. This Frontier Technologies proposal has broad national and international relevance through development of new methods for authentication of chemical identity and the subsequent superior ability to characterise numerous sample compositions.Read moreRead less

New Enantiomeric Separation Technologies for Natural Product, Pharmaceuticals and Environmental Pollutant Characterisation. 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.

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
