Ion Chromatography Columns Features

Several of our ion exchange columns are available packed with 4µm resin particles. This smaller particle size provides better resolution, faster run time, and more reliable results. The length of the column can be optimized for the desired results. Shorter columns can be used at higher flow rates to increase productivity without sacrificing performance, while longer columns can be used for higher resolution separations of complex sample matrices. These options allow you to optimize resolution and throughput for your application.

Our highly porous column resins offer more surface area per particle, providing more opportunity for analytes to bind to the resin surface. This high capacity enables the columns to handle high analyte concentrations, provide good resolution of weakly retained ions, enable analysis of high-ionic-strength samples, and load a larger sample volume without overloading and peak broadening. 

Our selection of Thermo Scientific Dionex ion chromatography columns ensures that we have the ideal columns for almost any type of analysis. We offer columns that can be used with hydroxide, carbonate and methanesulfonic acid (MSA) eluents. In addition to our Thermo Scientific Dionex IonPac IC columns, we offer unique column chemistries for high-resolution, high-efficiency analysis of biological molecules, such as amino acids and carbohydrates.

Our IC column portfolio includes columns for our Thermo Scientific Dionex ICS-6000 HPIC System that support running the system in Dual EGC mode. This mode uses electrolytic eluent generation technology to create highly reproducible, accurate KOH/KMSA eluent gradients that resolve mono-, di- and oligosaccharides and sialic acids.
