Simple techniques to preconcentrate samples for capillary electrophoresis/mass spectrometry

摘要：

Sample preconcentration for capillary electrophoresis(CE) can be done either before or after sample injection.Large volume sample stacking using an electroosmotic flow pump(LVSEP) is a widely used after-injection preconcentration technique removing the long sample matrix into the inlet side.However,due to the lack of an outlet vial,it was difficult to apply LVSEP to CE with electrospray ionization mass spectrometry(ESI-MS).We solved this difficulty by placing a vial supplying a run buffer during the matrix removal and sample stacking process but using a conventional sheath liquid CE/ESI-MS interface.
