General description

BIOshell 160 Å Peptide C18 columns are specifically engineered to provide efficient separation of peptides as well as small proteins. These columns contain advanced Fused-Core particles with pores strategically sized to 160 Å to enable optimized peptide diffusion. This attribute makes these columns an excellent choice for peptide mapping. Additionally, the sterically-protected C18 ligands provide extra stability allowing the columns to be used at an extended pH range (2-9) and high temperatures (up to 90 °C). This greatly expands the application range for the separation of biomolecules.
