摘要
Capillary zone electrophoresis with laser-induced fluorescence detection has been shown to give rapid separations with high resolution and sensitivity. These advantages are documented for catecholamines analysis in the present work, which shows that separation of subnanomolar concentrations of dopamine and noradrenaline (detection limits of 8.6 x 10(-11) M, corresponding to a detected amount of 143 zeptomoles of each catecholamine) can be performed in 82 s with an efficiency of several million theoretical plates.
