FIELD: medicine.
SUBSTANCE: invention refers to biology and medicine, namely to qualitative and/or quantitative indication of analytes. A device for analyte collection from a solution by concentrating it on magnetic particles comprises a flow chamber consisting of upper and lower passages comprising electrodes for generating an electric field perpendicular to a fluid flow in a fluid passage from a semi-permeable dialysis membrane arranged between the upper and lower passages, a magnetic field concentrator and a magnet for generating a magnetic moment in the concentrator.
EFFECT: ensured accelerated and higher detection sensitivity.
