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.
