Resin matrix: the finer and more uniform the particle size, the higher the resolution, but also the higher the backpressure (with the exception of the Source matrix);
Physical stability: new generation resins are more robust and can withstand high flow rates while maintaining a stable column bed volume and structure, eliminating the need for frequent column loading operations and improving reproducibility;
hemical stability: the new generation of resins can withstand extreme pH, high salinity, pro-solvents and organic solvents, facilitating the development of separation conditions and in-situ cleaning (CIP), greatly extending resin life and improving reproducibility.
