Abstract
Carbon nanotubes paste electrodes (CNTPE) prepared with short (1?5mlength) and long carbon nanotubes (5?20mlength) of 20?50 nm
diameter have demonstrated to be highly useful as detectors in flow injection analysis and capillary electrophoresis. Compared to the classical
graphite paste electrode, CNTPE improved the detection limits of dopac, ascorbic acid, dopamine, norepinephrine and epinephrine. The content
of agglutinant has shown to be an important variable in the preparation of these carbon nanotubes composites. Even when no substantial
differences were observed between the electrodes, those
