Olea europaea, meaning "European olive," is a small tree belonging to the family Oleaceae, occurring in the Mediterranean Basin. Olive oil is an essential component of a balanced diet because of its nutritional value. Among micronutrients, phenolic compounds did show important beneficial effects for human health.

Is there anything special I need to do to my HPLC system to use Ascentis Express?
1 risposta-
Nothing special is required to use Ascentis Express HPLC columns. To obtain the full benefits of Ascentis Express, one should minimize dispersion or instrument bandwidth in the HPLC system (tubing, detector flow cell) as well as confirm the detector response system is set at a fast level. For more information, request Guidelines for Optimizing Systems for Ascentis Express Columns (T407102)

Can I use Ascentis Express on a UHPLC system?
1 risposta-
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 flow rate should I use with Ascentis® Express HPLC Columns?
1 risposta-
Based on the minimum in the van Deemter curves, higher flows than 5um particle columns are required in order to maximize Ascentis Express column efficiency. The suggested starting point for flow rate for Ascentis Express columns: 1.6 mL/min for 4.6 mm ID; 0.8 mL/min for 3.0 mm ID; and 0.4mL/min for 2.1 mm ID.

Do I need special fittings and tubing to connect Ascentis® Express HPLC Columns?
1 risposta-
While operating pressures may not exceed the 400 bar (6,000 psi) capability of your traditional instruments, sustained pressures of about 200 bar (3,000 psi) will exceed the recommended pressure for conventional PEEK tubing and fittings at the column inlet. We recommend changing to stainless steel fittings in all high pressure locations and have designed special High Performance HPLC Fittings/Interconnects that will stay tight at pressures of 1,000 bar (15,000 psi) or greater, even when elevated column temperatures are employed.

Can Ascentis® Express HPLC Columns be used for LC-MS?
1 risposta-
Express Fused-Core™ particles were designed with LC-MS in mind. Even extremely short column lengths exhibit sufficient plate counts to show high resolving power. The flat van Deemter plots permit resolution to be maintained at very high flow rates to maximize sample throughput. All Ascentis stationary phases have been evaluated for MS compatibility during their development, and the Express phases are no exception. You can expect extremely low column bleed and background while maintaining longest possible column lifetime. A bonus of Ascentis Express columns for high throughput UHPLC and LC-MS is that they are extremely rugged and highly resistant to plugging, a very common failure mode for competitor columns.

What is the carbon load for Ascentis Express RP-Amide?
1 risposta-
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 RP-Amide is 3.0 micromoles/meter-squared.
