The present study demonstrates that native fluorescence detection combined with capillary electrophoresis separation at low pH provides high sensitivity (down to nanomolar), high resolution, high speed, and low interference for the analysis of catecholamines. Further, this method has been employed successfully for the measurement of the amounts of epinephrine and norepinephrine in individual bovine adrenal medullary cells. Application of this method to the study of neurochemistry is promising.
