Abstract:
The in-line combination of capillary electrophoresis (CE) with liquid microextration techniques, as single-drop microextraction (SDME), solid microextraction tecniques as, in-line solid phase extraction (SPE) and the use of pressure-assisted electrokinetic injection (PAEKI), as an electrophoretic preconcentration technique have been evaluated in the development of CE-based methods for the determination of different families of emerging organic pollutants (EOCs) in different kind of samples. The results showed that these strategies are adequate to improve the limited CE sensitivity, especially when it is used in combination with an ultraviolet detector is resolved in a simple and automatic easily. Therefore, we can emphasize that the use of these techniques is a useful strategy to improve the analysis of EOCs through CE.
