Frequently Asked Questions

Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
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.
When are additional phases expected?
Additional phases are being developed.The best way to track new products is to visitAscentis Express for the latest updates.
Can I use Ascentis Express on any type of HPLC system?
Ascentis Express HPLC columns are capable of use on standard HPLC systems as well as UHPLC systems.Columns are packed in high pressure hardware capable of withstanding the pressures used in UHPLC systems.
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.
How do I find price and availability?

What is the Department of Transportation shipping information for this product?
Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product.
What is the pressure rating for75 μmI.D. Ascentis®Express Capillary HPLC columns?
The 75 μmI.D. Ascentis® Express Capillary HPLCcolumnsarestable to operating pressures up to 8500 psi.
What is the carbon load for Ascentis Express C8?
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 C8 is 3.7 micromoles/meter-squared
