Ion chromatography device, Dionex

The Dionex IC1000 and IC1100 are ion chromatography systems engineered for the qualitative and quantitative determination of major inorganic anions and cations in aqueous matrices. The instruments utilize an isocratic eluent delivery system with a chemically inert, corrosion-resistant PEEK pump head coupled to a high-sensitivity conductivity detector optimized for ionic species monitoring. Both systems feature advanced electrolytic suppression technology that drastically minimizes background eluent conductivity while enhancing the signal-to-noise ratio. They are managed by the Chromeleon software package. The systems utilize high-capacity Dionex IonPac analytical columns (such as AS14/AS18 for anions and CS12/CS16 for cations) paired with matching guard columns. Detection sensitivity is maximized through the integration of Dionex ASRS or CSRS electrolytically regenerated suppressors, which continuously suppress eluent background conductivity and enhance analyte signals without requiring external chemical regenerants.

Principle of work
Ion chromatography is a very useful technique for qualitative and quantitative determination of ionic species in solution: cations, anions and polar molecules. This technique is based on the principle of chromatographic separation and difference in affinity of the ingredients in the sample to ion-exchange and sorption on column. Ion exchange takes place in the column packed with the stationary phase, which is actually an ion-exchange resin with active functional groups, positively or negatively charged. The corresponding counterions to a particular functional group is replaced by other ions of the same charge, or from the mobile phase, or eluent. The eluent is an inert medium which does not react chemically with the sample, and the sample is transferred from the ingredients of the column to the conductometric detector. Each ion exchange ion defines the equilibrium. The result is ion chromatography curve showing the dependence of the signal on time. Each ingredient has its own characteristic residence time in the column, so-called retention time. It is constant at constant conditions of ion chromatographic analysis. The small ions are eluted before the large ions, and also a monovalent before di- and tri-valent ions.
