Solid-phase extraction (SPE) was coupled to ion-trap mass spectrometry to determine clenbuterol in urine. For SPE a cartridge exchanger was used and, after extraction, the eluate was directly introduced into the mass spectrometer. For two types of ca

Publikováno v: Journal of capillary electrophoresis. 5(3-4)

The potential of micellar electrokinetic chromatography (MEKC) for the profiling of cocaine samples is described. An MEKC system containing sodium dodecyl sulfate (SDS) and methanol was optimized using a test mixture of cocaine, its common impurities
