摘要：
A potentiometric monitor incorporating a flow-through analysis channel has been developed based on the standard addition or subtraction principle. Programmed addition of standard or reagent was carried out at a given point of the flow-through system by current-programmed coulometry. A computer was used for data acquisition, for electric noise rejection, for signal recognition and for calculating the analytical results. The characteristics of the monitor system have been investigated under conditions optimised for the chloride determination, and the performance of it was checked by monitoring the chloride concentration in tap water.
