Yes, 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 F5 HPLC Columns for high throughput UHPLC and LC-MS are that they are extremely rugged and highly resistant to plugging, a very common failure mode for competitor columns.

General description
The pentafluorophenylpropyl stationary phase of Ascentis Express F5 provides a stable reversed phase packing with electron-deficient phenyl rings due to the presence of electronegative fluorines.In addition to forming pi-pi and mildly steric interactions, F5 phases also retain compounds by polar interactions. Ascentis Express F5 can be used for basic, acidic, or neutral compounds with alternate selectivity from C18.

Do I need special fittings and tubing to connect Ascentis® Express F5 HPLC Columns?
1 answer-
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.

Is there anything special I need to do to my HPLC system to use Ascentis® Express F5 HPLC Columns?
1 answer-
Nothing special is required to use Ascentis® Express F5 HPLC Columns. To obtain the full benefits of Ascentis® Express Columns, 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 Performance with Ascentis® Express HPLC Columns (T407102).

What flow rate should I use with Ascentis® Express F5 HPLC columns?
1 answer-
Based on the minimum in the van Deemter curves, higher flows than 5um particle columns are required in order to maximize Ascentis® Express F5 HPLC 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.

Can I use Ascentis® Express F5 HPLC Columns on a UHPLC system?
1 answer-
Ascentis® Express F5 HPLC columns are packed in a way making them suitable for these ultra high pressure instruments. In fact, Ascentis® Express F5 HPLC Columns outperform sub-2 μm micron columns on many applications since Ascentis® Express F5 HPLC Columns provide 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.
