Abstract
Home-made pyrolytic carbon film electrodes (PCFE) were tested in voltammetric experiments. Different drugs were analyzed by differential pulse voltammetry. In many cases the reproducibility of the signals is as satisfactory as by using glassy carbon electrodes (GCE). The cleaning procedure is very easy to accomplish by wiping off the electrode surface with a paper tissue dipped into methanol. The peak- to residual current rate is much better at the PCFE than at the GCE. Therefore the detection limit is lowered at the former.
