Questions

1–4 of 4 Questions  
  1. What is the carbon load for Ascentis® Express C18 HPLC Columns?

    1 answer
    1. Carbon load which is commonly referred to as %Carbon is misleading and not meaningful for Ascentis® Express. Since Fused-Core™ particle is unique in the sense that it has a solid core and porous shell, the %Carbon number can not be compared to traditional porous particles.  The carbon coverage for Ascentis® Express C18 is 3.5 micromoles/meter-squared

  3. Can I use Ascentis Express on a UHPLC system?

    1 answer
    1. Yes.  Ascentis Express columns are packed in a way making them suitable for these ultra high pressure instruments.  In fact, Ascentis Express outperforms sub-2 μm micron columns on many applications since Ascentis Express provides the benefits of sub-2 μm particles but at much lower back pressure.  These benefits include the capability of providing fast HPLC and higher resolution chromatography.  The Fused-Core particle consists of a 1.7 μm solid core and a 0.5 μm porous shell.  A major benefit of the Fused-Core particle is the small diffusion path (0.5 μm) compared to conventional fully porous particles. The shorter diffusion path reduces axial dispersion of solutes and minimizes peak broadening.
