4 Micron Small Particle Size IC Columns

Optimize speed and resolution in ion chromatography

Now you can optimize the speed and resolution of your run using small particle Thermo Scientific Dionex IonPac 4 micron (µm) IC columns. Column efficiency doubles when particle size is reduced from 8µm to 4µm. Available in various lengths, Dionex IonPac 4µm IC columns allow you to optimize faster runs with better chromatographic resolution. Dionex HPIC high pressure ion chromatography systems were designed to operate comfortably at the higher backpressures 4μm IC columns create.
