Single-drop microextraction (SDME) and large-volume sample stacking using an electroosmotic flow pump (LVSEP) were coupled with capillary electrophoresis/mass spectrometry (CE/MS) for sample cleanup and preconcentration. Without filtration or centrifugation of a soil sample containing debris, SDME using a pentanol acceptor
