Abstract : Analog and digital instrumentation have been developed for computer-controlled monitoring of multiple ion-selective electrodes in a flowing stream. Analog features include wide bandpass, low drift, and low noise, while the digital system features include multiplexing, signal averaging, computer-controlled data selection, and rigorous least-squares analysis of standard addition data for up to five simultaneous electrode inputs.
