MULTI-ANALYTICAL METHOD AND SYSTEM BASED ON IMPEDIMETRIC MEASUREMENTS.

摘要

The invention describes a system for the simultaneous detection and/or quantification of several analytes in a sample or for the simultaneous detection and/or quantification of an analyte in several samples, comprising: a multi-electrode chip (10) comprising a set of micro-electrodes (11a, 11 b, 11c, 11d); a single-duct cell (20) comprising a slot (21) containing the multi-electrode chip (10) and a duct (22) through which a fluid sample can flow sequentially over each of the micro-electrodes (11a, 11 b, 11c, 11d) of a multi-electrode chip (10) when it is contained in the slot (21); and a multi-duct cell (30) comprising a slot (31) containing the multi-electrode chip (10) and several separate ducts (32a, 32b, 32c, 32d) through which several samples can flow separately over each electrode (11a, 11 b, 11c, 11d) of the multi-electrode chip (10).
