Kinetex Core-Shell C18
Kinetex core-shell C18 columns offer increased efficiencies over traditionally porous C18 LC columns on HPLC/UHPLC systems
Kinetex Core-Shell C18
The Go-To Core-Shell Selectivity for Hydrophobic Compounds!

The Kinetex C18 is a well-rounded, all purpose core-shell column that produces increased efficiencies over traditional fully porous columns. Yielding remarkable chromatographic resolution, higher peak capacities, and greater sensitivity, so labs can get the most out of every HPLC or UHPLC analysis.

  • Compatible with All Analytical HPLC/UHPLC Systems*
  • Five Fully Scalable Particle Sizes Available
  • Excellent Reproducibility and Batch-to-Batch Confidence
  • USP: L1

*Kinetex analytical columns are compatible with all LC system with standard LC column end-fittings threaded in 10-32. Please contact us at Phenomenex.com/chat for any questions and information about fitting compatibility and any other column internal diameters.
