 Ascentis HPLC Columns for Small Molecules

Elevated HPLC Performance

We have placed heavy emphasis on optimizing Ascentis phases with relation to the three terms of the resolution equation: efficiency, retention and selectivity. However, our strongest emphasis has been on the most powerful term, selectivity. Together, Ascentis bonded phases have a wide range of selectivities. It is likely that one or more Ascentis phase will accomplish any small molecule HPLC separation. Packed in micro- to preparative hardware dimensions, Ascentis products cover all HPLC application areas, including the most sensitive trace-level analyses.

The general features of the Ascentis family include:

  • High purity, type B silica for inertness, reproducibility and stability
  • Modern bonding processes that optimize bonded phase coverage and maximize stability, while minimizing bleed and unwanted secondary interactions
  • Wide selection of bonded phase chemistries and bare silica
  • Phases with enhanced polar compound retention Compatible with LC-MS and all of today’s sensitive instruments and methods
  • Scalable selectivity from analytical to preparative
  • High surface area silica for high preparative loading capacity
