Minicomputer-based instrumentation for electroanalytical techniques

The system comprises a PDP 11/23 PLUS (16-bit) computer and a home-made electrochemical interface which includes digital/analog and analog/digital conversion circuits, a potentiostat, and programmable timers allowing fast data transfer. The software developed includes operating system routines and user-level programs for cyclic voltammetry and chronoamperometry. The whole system provides the user with a computer-aided execution of experiments, including potential waveform synthesis and collection and evaluation of responses.
