Resumen:
The main objective of this Doctoral Thesis is the development of different strategies to decrease the detection limits of capillary electrophoresis for the determination of pharmaceutical and personal care products. These strategies are based on electrophoretic and chromatographic preconcentration techniques, and the use of mass spectrometry as a detection system. The electrophoretic preconcentration techniques studied included sample stacking techniques and sweeping while the chromatographic preconcentration technique evaluated was in-line coupling between solid phase extraction and capillary electrophoresis. With respect to PPCPs, this Doctoral Thesis focuses specifically on non-steroidal anti-inflammatory drugs (NSAIDs), parabens and UV-filters. Another objective of this Doctoral Thesis is to study the suitability of the developed methodologies for the determination of PPCPs in environmental samples.
