General introduction

I obtained my Master of Science in Chemistry at Ghent University in 2012. For my master thesis, I conducted research at CHIS (Vrije Universiteit Brussel) under the mentorship of Prof. Eeltink, Prof. Desmet and Prof. Broeckhoven. The main focus of my thesis was the optimization of separation performance at 1200 bar, by using coupled core-shell particulate columns for the separation of small molecules (waste water pollutants) and biomolecules (peptides).


For my dissertation I will be focusing on the optimization of the detection limit and separation performance of multidimensional separations. Sample enrichment parameters (enrichment column size, mobile phase temperature, etc.) and design of enrichment device (Figure 1) will be investigated. One of the applications where sample enrichment is of big importance is for impurity profiling of drugs. Another application where, due to dilution effects, enrichment of analytes is very useful is for therapeutic protein profiling with comprehensive online 2D-LC.
