1. A glucose quantification device for determining the concentration of glucose in a liquid medium comprising a reference electrode;

  • a counter electrode and a working electrode with a semipermeable membrane immersed in a liquid medium in which at least one chemical entity is dissolved;

    a potentiostat for applying a measurement potential to the working electrode relative to the reference electrode corresponding to a measurement voltage during at least a portion of measurement period, and thereby causing said chemical entity to participate in an electrochemical reaction at the working electrode, said electrochemical reaction resulting in a impedance measurement evoked current, a measuring unit for said impedance measurement evoked current; and

    a means for comparing said impedance measurement evoked current with a predetermined value to obtain a comparison result.
