Ascentis® Express C18 HPLC Column
2.7 μm particle size, L × I.D. 10 cm × 2.1 mm

Ascentis® Express C18 HPLC Columns
C18 HPLC column for High Speed and High Resolution Applications

Ascentis™ Express C18 is the first choice for starting a new method. Ascentis Express HPLC columns, through the use of Fused-Core™ particle technology, can provide you with both the high speed and high efficiencies of sub-2 μm particles at lower system pressure. With identical conditions, the Ascentis Express C18 column performs more than 4X faster than a standard C18 column, for most applications. The combination of high efficiency and lower operating pressure benefits UHPLC (or other ultra high pressure system) users, as well as conventional HPLC users. The increased efficiency of Ascentis Express columns enables you to use shorter columns and reduce solvent usage/cost.

Similar columns from other manufacturers to Ascentis Express C18

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.
