Ascentis ES-Cyano

by Sigma Aldrich

Ascentis® ES-Cyano HPLC Column
3 μm particle size, L × I.D. 10 cm × 2.1 mm

Ascentis®
We have placed heavy emphasis on optimizing Ascentis phases with relation to the three terms of the resolution equation: efficiency, retention and selectivity. However, our strongest emphasis has been on the most powerful term, selectivity. Together, Ascentis bonded phases have a wide range of selectivities. It is likely that one or more Ascentis phase will accomplish any small molecule HPLC separation. Packed in micro- to preparative hardware dimensions, Ascentis products cover all HPLC application areas, including the most sensitive trace-level analyses.

Features and Benefits

Enhanced stability at low pH
Operates in reversed-phase, HILIC, and normal phase modes of chromatography
Low MS bleed
100% aqueous compatible
Available as 3 μm and 5 μm particles
Particle composition: Type B silica gel
Particle shape: Spherical

Extra stable for low pH mobile phases due to sterically protected phase.

Useful for selectivity in the reversed-phase mode, including π π and dipole-dipole interacting compounds. Can also be used HILIC mode and normal phase chromatography.

Similar columns from other manufacturers to Ascentis ES-Cyano

Up to 10 unique Brand families from other Vendors with the same Mode and the same Modification.

How similarity is calculated

Eligible families receive a weighted score from Modification (25%), Product Usage (20%), Carbon Load (15%), Endcapping (10%), Pore Size (10%), Surface Area (8%), pH Stability (8%) and Particle Size (4%). The score uses data available in both families and requires at least three comparable criteria, at least 50% data coverage and a minimum 55% score. A relevant active sponsor may appear first and is always labelled Sponsored.

A similarity score does not guarantee identical selectivity or performance. Confirm suitability under the intended method conditions.

No other-Vendor Brand family with the same Mode and Modification meets the comparable-data and similarity thresholds.
