N2 - The implementation of a pH-ISFET and a flow-through sandwich nitrate selective electrode (ISE) as a reference electrode in a flow-injection system for pH determination, is described. With this system, the linear working range extends from pH 1 to 13 with a sensitivity of 59 mV per pH unit and a relative standard deviation of 0.5%. To implement the sensor in the flow system, a special flow assembly which integrates the ISFET and the ISE has been designed. © 1992.
