A current recording unit for potentiostats
O.R. Brown · Journal of Physics E Scientific Instruments · 1972
An instrument is described which (i) enables cell currents to be recorded in analogue form by commercial recording equipment possessing a single input relative to earth, (ii) integrates these currents over any chosen period and (iii) converts the same currents to a logarithmic scale. The response and accuracy of the instrument are discussed. Cell currents of any magnitude below 3A are handled, although the logarithmic operation loses accuracy below 0.3 mu A The instrument can be used with most commercially available potentiostats.
