Eluent Suppressors for Ion Chromatography

A typical ion chromatograph consists of several compo-nents as shown in Figure 1. The eluent, which is conductive, is delivered to the system using a high-pressure pump. The sample is introduced, then flows through the guard, and into the analytical ion-exchange columns where the ion-exchange separation occurs.
