Merck: Ascentis® Express Products: Fast HPLC Columns

A Breakthrough in HPLC Column Performance

Based on Fused-Core® Particle Technology, Ascentis Express HPLC columns offer significant performance benefits over popular columns based on totally porous particles.

Ascentis Express columns based on 2.7 μm particles provide the high efficiency separation of sub-2-μm particles, but at higher speed and half of the backpressure. This lower pressure means that Ascentis Express can be run on all HPLC systems including conventional as well as UHPLC systems.

Newly launched Ascentis Express C18 and F5 columns based on 5 μm particles provide faster, more efficient separations compared to popular 3 μm and 5 μm totally porous particles. Learn more
