Product to Increase Throughput & Productivity


Solid Core Column (2.0um, 2.7um and 5.0um particle size)


Finally a column product line that can be used in both systems of UHPLC (UPLC‘s) and HPLC systems. One column for all. The Ascentis Express is an addition to the long line of superior Supelco technology columns but with solid core particles. These columns offer a much higher efficiency as compared to conventional fully porous particles and are considered the next step for chromatography columns of the future. Higher efficiencies means better separation power between analytes with lower backpressure enabling faster analysis while meeting demanding separation requirements. All in all far better peak shapes.


  • Comes in either 2.7um particle sizes (suitable for both UHPLC/UPLC and HPLC) systems as well as 1.6um particle sizes (solely for UHPLC/UPLC) systems. Added bonus, 5.0um particle size columns also available for users that simply are reluctant to change their method.
  • Comes in 12 different chemistries for octagonal separations which covers analysis for small molecules right up to biomolecule separations.
  • Various column dimensions of different internal diameter and length available.

  • Exceptional peak shape and loading capacity
  • Improve signal-to-noise performance
  • Chemically stable at low pH
  • Higher efficiency
  • Increased resolution
  • Scalability from UHPLC/UPLC to HPLC
  • Seemingly lower back pressure as compared to fully porous particle columns
  • Lot to lot reproducibility and longer shelf life
  • 2.0um particle size core shell technology gives 40% higher efficiency as compared to fully porous 1.7um particles
  • 2.7um particle size core shell technology gives 90% efficiency as compared to sub 2um fully porous particles
  • 5.0um particle size column provides efficiency higher than that of fully porous 3.0 particle size of the same dimension with lower backpressures. Design specifically for those chemist who are reluctant to change their method but looking into far better efficiency as compared to fully porous 5.0um particle size column
  • More rugged column, longer shelf life and not easy to clog
