Flow-through field effect transistor structures are utilized as tunable, electrochemical ion- selective sensors to analyze the ionic content of channel fluids from drain-source current measurements and gate conductance spectroscopy. Compared to ion-selective electrodes in a flowFET its gate region acts as a programmable membrane determined by the gate potential. DC measurement results using aqueous solutions of NaCl and CuSO4 in the 10-4-10-7 molar range are discussed.
