Transducer modules for use in a blood analysis instrument and methods for analyzing a blood sample. A difference from the prior art is that each adaptation scheme defines a set of different transmission formats, wherein each transmission formats is a combination of at least two of the parameters the source codec bit rate, the packet rate, the number of frames of each packet, and the level of redundancy. Each of the plurality of Active Front End units can be adapted to convert alternating current voltage to a DC voltage. This results in higher flow rate through the stack, elimination of the pressure drop limitation, and reduction of power consumption per unit volume of water.
