Abstract: The present disclosure refers to a sensor assembly for an IVD analyzer, the sensor comprising two opposite substrates with at least one fluidic conduit for receiving a sample. The electrodes of different types of electrochemical sensors are arranged on the two opposite substrates facing the at least one fluidic conduit for coming in contact with the sample and determining sample parameters, wherein the counter electrodes and the reference electrodes are formed on one substrate and the working electrodes are formed on the opposite substrate. This achieves optimal sensor-working conditions in terms of a homogeneous and symmetrical electric field density and enables a sensor assembly with simpler geometry and smaller size.

Abstract: The present disclosure refers to a sensor device, a method of operating the sensor device and an IVD analyzer for receiving the sensor device for determining chemical and/or physical characteristics of a fluid. The sensor device comprises at least two fluidic conduits for repeatedly receiving fluids, each fluidic conduit comprising at least one sensory element arranged such as to come in contact with a fluid in the respective fluidic conduit. In particular, the fluidic conduits comprise different sensory elements, respectively, wherein the sensory elements are separated in the respective fluidic conduits according to compatibility or susceptibility to deterioration or operating temperature. Alternately, the fluidic conduits comprise at least in part the same sensory elements, wherein the sensor device is operated in a primary operating mode and in response to a trigger event, switches to an extended operating mode.
