The proposal consists of several related projects which are unified by the ultimate desire to develop robust miniature systems and devices suitable for on-site and field analysis. Firstly, the trapping of ions for preconcentation in capillary electrophoresis by employing two opposing transport mechanisms, electrokinetic mobility and hydrodynamic flow, is to be studied. Secondly, a capacitively coupled on-capillary microplasma for atomic spectroscopy is to be further developed. It is intended to develop a miniature optical emission spectrometer for the determination of trace metals. Thirdly, a sensitive, field capable detector for gas-chromatography is to be developed, which is based on analyte ionisation through an electrical discharge. Fourthly, liquid-liquid extraction of organic ions using a lipophilic membrane and the application of a voltage to enhance the rate of extraction rather then relying on slow passive diffusion is to be further studied.Fifthly, the use of novel deep UV-LEDs for analytical purposes, namely for detection in capillary electrophoresis, and for sensing of gases and vapours by direct absorbance measurements and by photoacoustic spectroscopy, is to be explored.
