1. Electrochemical Aspects of Miniaturized Analytical Platforms
Abstract : This thesis ties some electrochemical aspects of development and fabrication of an analytical system on a microchip together. These aspects develop through the fundamentals of amperometric detection in microsystems and microfabrication via the interaction of electrochemical detection and electrophoretic separation finally to the interfacing of a microsystem to the macro world.

2. Characterization of dissolved organic matter : An analytical challenge
Abstract : Dissolved organic matter (DOM) is the prevalent form of organic carbon in most aquatic environments. It is an ultra-complex mixture that plays a crucial role in global carbon cycling. Despite its importance it is still poorly understood due to its extreme heterogeneity and intricacy. READ MORE

3. Fundamental Studies on Direct Injection Nebulisers for Sample Introduction in ICP Spectrometry : Aerosol Properties, ICP Characteristics and Analytical Performance
Abstract : The performance of different types of nebulisers: Vulkan direct injection nebuliser (Vulkan DIN), direct injection high efficiency nebuliser (DIHEN), microconcentric nebuliser coupled to cyclonic or double pass spray chamber (MCN-C or MCN-DP, respectively) was investigated and compared when used for sample introduction to ICP-MS or ICP-OES. With ICP-OES, in axial viewing mode, intensity distributions across the radius of the plasma (radial intensity profiles) were determined for different spectral lines with Esum 1. READ MORE

4. Exploring the fate of emerging contaminants during hydrothermal regeneration of carbonaceous adsorbents
Abstract : Wastewater from households and industries commonly contain emerging contaminants that are not easily removed by most wastewater treatment plants. These contaminants can be removed through adsorption onto adsorbents, such as activated carbon or biochars. READ MORE

5. Development of Enhanced Analytical Methodology in Pesticide Chemistry
Abstract : The analysis of pesticide residues in fruit, vegetables, rape seed and water has been improved using developments in sample handling and analytical techniques. The method development is associated with analytical difficulties, since pesticides currently used in agriculture represent a variety of chemical classes having very different physico chemical properties.
