Abstract
Electrochemical detection of short-chain aliphatic alcohols separated by liquid chromatography demonstrates close sensitivities at gold and platinum working electrodes. Addition of acetonitrile in the eluent decreases the sensitivity of detection (peak area) at the gold electrode but improves the apparent sensitivity (peak height) by a consequent decrease of retention time. At the platinum electrode, the detection was completely inhibited by traces of acetonitrile. Gold was therefore chosen to investigate the amperometric detection of flavor -active alcohols, and particulary of terpenols, separated by reversed-phase chromatography using an acetonitrile-water eluent
