UHP columns are made of 1.9μm silica particles and resist pressures up to 1000 bar (15000 psi), and are therefore suitabe for UHPLC.
UHP ASB C18: excellent peak shape for basic compounds and compatible with 100% aqueous mobile phase
UHP HILIC: compatible with 100% aqueous mobile phase and superior retention of polar compounds
