Ascentis Express RP-Amide

by Sigma Aldrich

Ascentis® Express RP-Amide HPLC Column
2.7 μm particle size, L × I.D. 10 cm × 2.1 mm

Ascentis® Express RP-Amide HPLC Columns
While the Ascentis™ Express C8 and C18 provide classic reversed-phase selectivity, the RP-Amide phase provides alternate reversed-phase selectivity, improved peak shape for bases, 100% aqueous compatibility, and LC-MS compatibility, to our high speed HPLC column line based on Fused-Core™ particle technology. Ascentis Express RP-Amide provides increased selectivity for polar compounds, especially those that can act as a hydrogen bond donor.

Similar columns from other manufacturers to Ascentis Express RP-Amide

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.
