HPLC column developed in the Czech Republic. HPLC column particles are continuously analysed by SEM.

Main particle characteristics:

  • •Close proximity to a sphere.
  • •Highly effective endcapping.
  • •No broken particles.
  • •Robustness to high pressures.
  • •Lot-to-lot reproducibility.
  • •Unique modern embedded phases.

Column hardware:

  • •Electropolished with very low Ra reduces wall effect.
  • •Rated up to 140 MPa (20 000 psi, 130 bar), ideal for UHPLC applications.
