Amperometry hydrogen peroxide determination

Kunnecke and Schmid [40] introduced a gas-diffusion separation system combined with an immobilized alcohol oxidase column used for the determination of ethanol in beverages by amperometry. Ethanol vapour from the samples diffused through a silicone-modified polypropylene membrane and was collected in a potassium phosphate buffer acceptor stream before passing through the immobilized enzyme column where the ethanol was transformed into hydrogen peroxide. The peroxide was determined using an amperometric detector with excellent precision (cf. Sec. 8.4). [Pg.147]
