Supelco® Ascentis® Express C18 HPLC and UHPLC Columns

New Product

Ascentis® Express C18 high-speed, high-performance liquid chromatography columns are based on the highly efficient Fused-Core® particle design.

The Fused-Core® particle provides a thin porous shell of high-purity silica surrounding a solid silica core. This particle design exhibits very high column efficiency due to the shallow diffusion paths in the 0,5 µm thick porous shell and the highly uniform overall particle size.

The densely bonded, extensively endcapped dimethyloctadecyl stationary phase of Ascentis Express 5 μm C18 provides a stable, reversed-phase packing that can be used for basic, acidic or neutral compounds.

An Ascentis® Express C18 validation pack makes it easy to demonstrate method reproducibility on three different lots. The validation pack contains a kit with three columns - one from each of three lots of bonded phase. And with Ascentis Express columns, you can be assured that all three columns will meet your expectations.

: Supplied with column test certificate inside the box.
