Capillary electrophoresis (CE) coupled to mass spectrometry (MS) is becoming increasingly important as analytical separation technique. In this thesis, 2D separation methods were developed in order to overcome limitations of CE-MS such as potential interference with electrospray ionization, low concentration sensitivity, and in particular cases deficient resolution and separation efficiency. These 2D methods include CE-CE-MS, liquid chromatography (LC)-CE-MS and CE-ion mobility mass spectrometry (IM-MS) for the analysis of small pharmaceuticals, intact proteins and glycans.
