Ascentis Express

  • Outperforms other smaller sub-2 μm particles in efficiency and addresses other disadvantages inherent in smaller sub-2 micron UHPLC columns
  • Delivers perfect balance of pressure and performance ideal for faster small molecule analysis on any UHPLC system
  • Available in C18, F5, OH5, and HILIC 5i phases

With the addition of 2.0 µm Ascentis Express UHPLC columns, we now offer three U/HPLC Fused Core® particle columns, making the Ascentis Express column line truly scalable from UHPLC to legacy HPLC systems.

Ascentis Express F5

The F5 pentafluorophenylpropyl stationary phase provides a stable reversed phase packing with electron-deficient phenyl rings due to the presence of electronegative fluorines. In addition to forming pi-pi and mildly steric interactions, F5 phases also retain compounds by polar interactions.

Ascentis Express F5 can be used for basic, acidic, or neutral compounds with alternate selectivity from C18.

Ascentis Express OH5

The OH5 stationary phase is a highly polar ligand that possesses 5 hydroxyl groups tethered to the silica via novel proprietary linkage chemistry. The high performance material provides a UHPLC column that can be used for traditional normal phase separations using non-polar, totally organic mobile phases or for aqueous normal phase chromatography with the typical mobile phases for hydrophilic interactive liquid chromatography (HILIC) or basic, acidic, zwitterionic, or neutral compounds.

Ascentis Express HILIC

The Ascentis Express HILIC or bare silica stationary phase provides a UHPLC column that can be used for traditional normal phase separations using non-polar, totally organic mobile phases or for aqueous normal phase chromatography with the typical reversed-phase mobile phases for hydrophilic interactive liquid chromatography (HILIC) of basic, acidic, or neutral compounds.
