N2 - The fast chemical response of the pH-ISFET makes the device an excellent detector in analytical chemistry. The time response of ISFETs, with Al2O3 at the pH-sensitive gate insulator, is determined in a flow injection analysis system. Application of an ISFET and a glass electrode are compared in rapid acid-base titrations and in a coulometric system for stable pH control. Finally, a method is described that combines both the stability of the glass electrode and the fast response of the ISFET.
