Working Principle

The principle of ion chromatography separation is based on the reversible exchange between dissociable ions on the ion exchange resin and solute ions with the same charge in the mobile phase, and the difference in affinity of the analyte solute for the exchanger. It is suitable for separating hydrophilic anions and cations. For example, in the separation of several anions, after the sample solution is injected, it first undergoes direct ion exchange with the ion exchange sites on the analytical column (i.e., it is retained on the column). For instance, when using NaOH as the eluent to analyze F-, Cl-, and SO42- in the sample, the anions retained on the column are replaced by OH- groups in the eluent and eluted from the column. Analyte ions with weak affinity for the resin are eluted sequentially before those with strong affinity. This is the ion chromatography separation process. The eluent passes through a chemical suppressor to minimize the background conductivity from the eluent, resulting in a large and accurately measurable conductivity signal when the analyte leaves the conductivity cell.
