span lang="en" style="font-family: "Times New Roman"; font-size: 12pt;">Carbon nanotubes paste electrodes (CNTPE) prepared with short (15 mm length) and long carbon nanotubes (5-20 mm length) 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 obse
