Chemical sensors for long-term use can only be applied as part of a complete system that performs sampling, calibration and signal processing. Minaturization of such systems leads to improved response times and a reduction in sample volume and reagent consumption. Ion-sensitive filed effect transistors (ISFETs) are well suited for use in small volume flow-through detectors. With the application of micromachined silicon structures such as pumps and flow manifolds for fluid handling, an important reduction in the overall size of the analysis systems can be achieved.
