FIELD: chemistry.
SUBSTANCE: system consists of two peristaltic pumps, a loop-containing injector, a flow amperometric cell with includes a biosensor, a potentiostat. As the biosensor, the electroanalytic system contains a lactate biosensor. The injector loop includes an accumulative column.
EFFECT: increase of selectivity and sensitivity of determination, reduction of the limit of lactate detection.
