1. Analytical Aspects of Atmospheric Pressure Ionisation in Mass Spectrometry
Abstract : The actual signal recorded with an analytical instrument is not always a true reflection of the analysed sample. In this thesis a further insight of the atmospheric pressure ionisation processes electrospray (ESI) and atmospheric pressure chemical ionisation (APCI) has been endeavoured, to provide a deeper understanding of and ways to minimize this bias.

2. Analytical Pyrolysis - Studies of Sulfur in Coal and Pulp
Abstract : Sulfur in coal and pulp have been characterized using pyrolysis–gas chromatography with a sulfur-selective flame photometric detector (Py–GC/FPD). The samples (50–150 µg) were pyrolyzed at temperatures between 300 and 1400°C usually followed by a combustion in oxygen at high temperature (>1000°C). READ MORE

3. Variance Reduction in Analytical Chemistry : New Numerical Methods in Chemometrics and Molecular Simulation
Abstract : This thesis is based on five papers addressing variance reduction in different ways. The papers have in common that they all present new numerical methods. READ MORE

4. Retention time predictions in Gas Chromatography
Abstract : In gas chromatography, analytes are separated by differences in their partition between a mobile phase and a stationary phase. Temperature-program, column dimensions, stationary and mobile phases, and flow rate are all parameters that can affect the quality of the separation in gas chromatography. READ MORE

5. Long-Term Simulation of Coastal Evolution
Abstract : There is a strong relationship between regional sediment transport and the local processes at tidal inlets and around coastal structures. Many coastal projects require quantitative understanding of these processes and the interactions between them. READ MORE
