Abstract
A nitrate sensor was manufactured on the basis of a field-effect trans istor with a Ta2O5 gate, ion-sensing polyvinyl chloride membrane, and a protective intermediate polymer coating. The sensor is unaffected by pH in the range 1-9; its service time is no less than 4 months. The o ther analytical characteristics of the sensor are similar to those of the corresponding nitrate-selective electrode. The study was performed on an automated laboratory setup. The potentialities of the setup are discussed.
