Ion chromatography without suppressor

In ion chromatography without a suppressor the conductivity of the eluent is no longer suppressed chemically but rather by electronic means. Fig. 67 is a schematic representation of the structure of a modern conductivity detector. 

As a result of the electronic compensation of the background conductivity, the full dynamic range of a detector of this type is retained. Today, ion-
