Methods and apparatus for electrochemical measurements

摘要: A method for the electrochemical determination of reducing sugars content an aqueous solution in a thin layer measuring device, preferably capillary fill wherein inner surface device is coated with soluble redox mediator, including means producing alkaline environment within device. In preferred mediator comprises potassium ferricyanide providing ions saturated and lithium hydroxide excess amount from 1 to 3 molar. The invention also provides having guard electrode between reference working electrodes.
