Abstract: A H2O2-selective electrode (Instrumentation Lab., Milan) was coated with L-lactate oxidase as active ingredient, immobilized on a nylon net and protected by a cellulose acetate dialysis membrane, and was applied in the determination of lactate in milk in a flow injection analysis system in which the flow rate was 0.2 mL min-1, the detector cell was of ~40 µL dead volume and amperometric detection was at +0.65 V vs. a Ag - AgCl reference electrode. The carrier stream was 0.1 M phosphate buffer at pH 7.0. The calibration graph was rectilinear up to 75 µM-lactate.
