HALO® BIOCLASS ES-C18 Peptide columns made with innovative Fused-Core® particle technology are ideal for both ultrafast- and ultrahigh-resolution separations of peptides and polypeptides up to 20 kDa. HALO® peptide columns offer comparable peak capacity to sub-2 μm non-core columns at 40 to 50% back pressure (2.7 μm), and 20% higher peak capacity than sub-2 μm non-core columns at comparable back pressure (2 μm). HALO 160 Å peptide columns are optimized for high performance in HPLC, UHPLC and LCMS peptide applications.
- Ideal for tryptic digests, post-translational modifications (PTMs), polypeptides
- Alternate selectivities with HALO® Peptide ES-C18, ES-CN, and Phenyl-Hexyl phases
- HALO® Peptide columns can be used in series to increase peak capacity for UHPLC and HPLC analyses of complex tryptic digest samples
- Particle Sizes: 2, 2.7 or 5 μm superficially porous particle silica ( 'solid-core', 'core-shell')
HALO® guard columns are available for this phase.
