Phase Detail
Kinetex Core-Shell Polar C18 Column
With Kinetex core-shell polar C18 columns, you get an L1 column with unique polar retention. Upgrade to polar C18 HPLC columns for faster operations.

Kinetex Core-Shell Polar C18 Column

Increase Polar Selectivity and Performance!

The Kinetex® 2.6 µm Polar C18 is a core-shell based particle with a polar modified surface and a C18 alkyl phase. This versatile column can easily upgrade existing fully porous 5 µm and 3 µm methods to shorten run time, increase sensitivity, and even provide greater resolution with much higher efficiency levels. Combined with being 100 % aqueous stable, the Kinetex Polar C18 is a unique column that combines performance and selectivity.

  • Compatible with All Analytical HPLC/UHPLC Systems*
  • L:1 C18 with Unique Polar Retention
  • Compatible with 100 % Aqueous Mobile Phases
  • USP: L1

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

Increase Polar Retention and Hydrophobic Selectivity

Increase polar selectivity without sacrificing hydrophobic selectivity with the Kinetex Polar C18. The Kinetex Polar C18 is an excellent all-purpose, 100% aqueous stable phase for use with multi-compound mixes that contain polar and non-polar compounds, or even single class methods that have closely related compounds, impurities, or metabolites.
