摘要: Catecholamines were analysed in aqueous and alcoholic non-aqueous solutions by capillary electrophoresis electrophoresis-mass spectrometry using sheathless nanospray coupling. Decreases the electrophoretic mobilities of catecholamines electroosmotic observed from water to 1-propanol. Separations more efficient all media than water. The diffusion coefficients different determined. solvent had little effect on sensitivity UV or MS detection. Both methods successfully applied analysis urine samples.
