Field of study
A rapid, simple and economic method was developed, which combines the specificity
of enzymes with the high sensitivity of HPLC. Therefore sample pretreatment is reduced
to simple dilution or extraction steps.
In this work oxidases for alcohol, glucose, oxalic acid, ascorbic acid and galactose
were immobilized and used as biosensors. Food samples were fruit juices and vegetable
products, soft drinks and wine. The detection limit e.g. for oxalic acid was in the
picomol range
