Flow-cell system for small scale electrosynthesis was developed and fu
nctional features are discussed. The system consists of a pump, substr
ate solution injector, electrolysis cell with a column electrode, pote
ntiostat and recorder. Carbon fiber of Carbon Cloth GF-20-P7 (Nippon C
arbon Co., Ltd.) served as the working electrode. System efficiency wa
s assessed by electrolysis of potassium hexacyanoferrate(III) and dl-a
lpha-tocopherol.
