| Abstract: | Multifunctional ISFETs are used in testing the performance of several nitrate-sensitive polymeric membranes simultaneously. By mounting the ISFET in a miniature flow-through cell, a continuous dilution technique can be used to obtain calibration curves and selectivity coefficient data for several membranes under identical conditions. |
