Dionex: Benefits of using 4 μm Particle-Size Columns

Typically ion chromatography columns use resin particles ranging from 7–9 μm in diameter. Recent developments in resin technology have allowed the use of 4 μm resin particles in ion exchange columns. In this application note, the use of Thermo Scientific Dionex IonPac 4 μm particle-size IC columns is discussed in relation to the optimization of chromatographic speed and resolution with higher accuracy and easier integration.
