Abstract
This research program encompasses two research sections: (A) Electrochemical sensors and (B) Hyphenated and automated analytical systems. Program section (A) encompasses fundamental studies and development of mainly voltammetric, amperometric and potentiometric sensors. These include: (a) Development of micro- and ultramicroelectrodes based on carbon and metal fibers and other appropriate materials, with an emphasis on new fabrication and isolation routes (e.g. new micro-technologies, new materials, new coating principles), and on new approaches to electrode surface modification based on inorganic and organic polymer films. This further involves the characterization, testing and control of the produced microelectrodes by means of electrochemical, optical and spectroscopic methods. Research into the applicability of the developed microsensors (electrochemical measurements in extremely small volumes and locations) in areas such as bio-medicine, high technology and the environment is also included. (b) Development of composite and printed carbon based electrodes. This also includes research on various inorganic and organic modifiers as possible preconcentration and/or electrocatalytic mediators, and on their potential applications in selected analytical fields (e.g. food, agriculture, pharmaceuticals, etc.). (c) Development of new film electrodes based on different materials. This focuses on new sensing materials and their possible combinations, as well as on using new methods of active layer deposition (e.g. sol-gel, dispersion). Program section (B) encompasses: (a) Fundamental studies and development of methodologies for coupling (i) separation and/or sample preparation techniques (ion and liquid chromatography, capillary electrophoresis, flow-injection analysis) and (ii) various detection techniques (electrochemical, ICP-mass spectroscopy, thermal lens spectrometry). This also includes analytical studies of selected organic and inorganic substances in complex samples of different origins. (b) Development of a new flow-injection system based on computer controlled measurement with an integrated automatic calibration procedure, and research on the practical use of a modified flow-injection system (the so-called sequential injection analyser). (c) Development of corresponding PC software programs and chemometric methods (e.g. theoretical processing and modelling, experiment design and optimization, data processing and/or result prediction, etc.) for automation of hyphenated analytical systems, as well as research into their routine applicability in solving selected problems using ion chromatography.
