The HALO Peptide ES-CN bonded phase is a fully endcapped, sterically-protected cyanopropyldi-isopropylsilane, which offers alternative selectivity for peptides up to 20 kDa.

Advantages
  • Ideal pore size (160 Å) for both ultrafast and ultrahigh resolution separations of peptides and polypeptides
  • Outperforms non-core 3 µm, 300 Ǻ columns in terms of peak width, peak capacity, and peak height (see chromatogram 1 below)
  • Delivers comparable peak capacity to sub-2-µm non-core columns at 40–50% back pressure
  • Offers different selectivity compared to the ES-C18 (see chromatogram below)
  • Improved retention for polar peptides
  • pH range:  1–8
  • Stable up to 90 οC at low pH
  • Available in 2.7 and 5 µm particle sizes for UHPLC and HPLC separations
