For ion analysis, nothing compares to a Dionex ion chromatography system. Laboratories using RFIC^™ systems spend less time on equilibration, calibration, method verification, troubleshooting, and consistency checks because the systems minimize unintentional variations in the preparation of eluents and regenerants. RFIC systems not only reduce the manual labor of IC, they make it easy to learn and easy to use.

Dual ion chromatography is a broad term involving many applications. Dual IC involves applications such as two-dimensional ion chromatography (2-D IC), as well as dual analysis, using simultaneous or sequential injection. 2-D IC is a dual-column technique to enhance analyte selectivity and sensitivity. One example of this application is the detection of low-level toxic compounds in a matrix with interfering analytes.

Dionex Reagent-Free^™ ion chromatography (RFIC) systems combine IC with electrolytic sample preparation (RFIC-ESP^™). All three systems can be equipped with optional 6- or 10-port valves to automate IC sample preparation, and support 2 mm and 4 mm chemistries without pump head changes.
