The technique is reasonably rapid and simple to perform. The calibration curve is linear in the concentration range from 1.0 to 20 μmol/l, the reproducibility (R.S.D.) at 10 μmol/l l-lactic acid is 1.34% (n=6) and the detection limit is 0.29 μmol/l (k=2). The method can possibly be used for monitoring l-lactate or l-lactic acid in food industries and clinical laboratories.
