AB-305 Checking surfactant electrodes   
Checking surfactant electrodes 

Methods for testing the condition of electrodes for surfactant titration are presented. For ionic surfactant electrodes, SDS is titrated with TEGOtrant, for cationic surfactant electrodes TE-GOtrant with SDS and for NIO surfactant electrodes PEG 1000 with STPB. With Surfactrode Resistant electrodes and Surfactrode Refill electrodes a titration of SDS with TEGOtrant is performed.
An appropriate criterion is the height of the potential jump and of course the shape of the titration curve.
