Building a low-cost standalone electrochemical instrument based on a credit card-sized computer

Abstract

A low-cost, standalone electrochemical instrument was built from a credit card-sized computer and inexpensive A/D and D/A converter chips. The instrument is capable of cyclic voltammetry and constant potential electrolysis, with the potential range of -4 to +4 V and the current range of 1 μA to 20 mA.
