A concept for the development of myTAS modules is presented which combines different transducer principles aiming at five model parameters of water control. Enzyme layers and ion-selective coatings, ISFETs, amperometric electrodes and optical cells, micropumps and micro channel systems, sample pretreatment and control electronics have been integrated in such a way that a small and light-weight analysis system for quasi continous monitoring can be achieved which consumes only small amounts of carrier and calibration solutions and has a low power consumption.
