Ion exchange is a separation technology. Thedissociatable ions on ion exchange resin exchange reversibly with the solute ions with the same charge in mobile phase. Ions are separated because of their difference in affinity to ions exchangers. So ion chromatograph is generally applicableto the separation and detection ofhydrophilicanions and cations. After the sample is injected, the ions to be analyzed are exchanged with dissociatable ions on the ion exchange resin at first (i.e. retained on the analytical column). When NaOH solution is used as eluent to analyze FgChand S042~ in the sample, the...
