Brownlee SPP Peptide ES-C18
– 15 columnsSay goodbye to the limitations of traditional columns. Break free from the constraints of your Liquid Chromatography instrument. With Brownlee Superficially Porous Particle (SPP) columns, you can achieve sharper peaks and faster separation results without changing instruments, worrying about high backpressure or compromising column longevity.
With their unique particle composition, only Brownlee SPP columns offer you the freedom to push your process farther.
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. Sterically protected ligand (isobutyl - side chains), results in an Extra Stable bonded phase at low pH where most peptide separations are performed.
