1. Interfacing HPLC with MALDI- and ESI-MS for Automated High Sensitivity Analysis of Proteins and Peptides
Abstract : The research described in this thesis has an interdisciplinary approach dealing with chemical, biological, and technical issues. One objective was to interface miniaturized liquid chromatography (LC) to mass spectrometry, i.e. MALDI-TOF MS and ESI-MS, in an unattended mode for high sensitivity determination of proteins and peptides.

2. Microactuators for Powerful Pumps
Abstract : When paraffin wax melts it exhibits a large, relatively incompressible volume expansion. This can be used in microactuators for strong and large displacements, a rare combination among actuators. Furthermore, paraffin is inexpensive, inert and environmentally friendly, as well as easily processed and actuated. READ MORE

3. Sample Handling Techniques in Biological and Environmental Applications Emphasizing Biomolecular Recognition and MALDI-TOF MS
Abstract : The use of restricted access media and other stationary phases for clean-up and trace enrichment of environmental samples coupled on-line to liquid chromatography using diode array detection as well as thermospray MS is described. This on-line configuration was compared with commercially available ELISAs for the determination of triazines in complex matrices, showing superior precision and accuracy with the chromatographic method.
