Brownlee SPP 2.7 ?m Peptide ES-C18 4.6 X 30 mm

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. The ligand was chosen due to its sterically protected bonding technology that inhibits acid hydrolysis of the siloxane bonds, even under extremes of high temperature and low pH.

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 columns use 2-µm frits
  • Can exceed performance of sub-2-µm particle size columns on most standard 6000 psi HPLC systems
  • Can be used on UHPLC system at pressures up to 9000 psi Longer columns can be used for very high column efficiencies on UHPLC systems
  • Optimization kits available for Series 200 and Flexar LC systems to increase application efficiencies
