What is special about Ascentis Express?
Ascentis Express columns provide a breakthrough in HPLC performance. Based on Fused-Core particle technology, Ascentis Express provides the benefits of sub-2 μm particles but at much lower backpressure. 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.
Can I use Ascentis Express on a UHPLC system?
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.

What is the carbon load for Ascentis® Express C18 HPLC Columns?
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
What is the pressure rating for 300 μm I.D. Ascentis® Express Capillary HPLC columns?
The 300 μm I.D. Ascentis® Express Capillary HPLC columns are stable to operating pressures up to 6500 psi.
