Grom Resin is a group of polymer-based HPLC columns engineered for high chemical stability across a wide pH range, making them ideal for challenging separations that involve extreme pH, aggressive mobile phases, or highly polar analytes. Unlike silica-based materials, Grom Resin phases are built on cross-linked polymer particles, ensuring mechanical robustness, long column lifetime, and versatile selectivity options such as reversed-phase and ion-exchange modes.
