Building a Low-cost Standalone Electrochemical Instrument Based on a Credit Card-sized Computer

摘要

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.
