Features and Benefits Solid inner core, porous silica outer shell, shorter diffusion path Very high efficiencies at moderate back pressures   Nearly twice the efficiency of 3-µm particle columns As robust as columns packed with 5-µm particles because

Sterically protected ligand (isobutyl - side chains), results in an Extra Stable bonded phase at low pH where most peptide separations are performed. The 160 Angstrom pore size was specially chosen for the molecular weight range of peptides.
