HALO Peptide ES-C18 bonded phase is a non-endcapped, sterically-protected octadecylsilane phase for ultrafast and high resolution of peptides and polypeptides up to 20 kDa.

Advantages
  • 160 Ångstrom pore size
  • Outperforms non-core 3 µm, 300 Å columns in terms of peak width, peak capacity, and peak height (see chromatogram 1 below)
  • Offers comparable peak capacity to sub-2-µm non-core columns at 40–50% back pressure
  • Columns can be used in series to increase peak capacity for UHPLC and HPLC analyses or complex tryptic digest samples (see chromatogram 2 below)
  • pH range:  1–8
  • Stable up to 90 °C at low pH
  • Available in 2.7 and 5 µm particle sizes for UHPLC and HPLC applications
