Kinetex Core-Shell C18 HPLC Column
C18 HPLC Column - Kinetex core-shell C18 columns offer increased efficiencies over traditionally porous C18 LC columns on HPLC/UHPLC systems

Kinetex Core-Shell C18 HPLC Column

The Go-To Core-Shell Selectivity for Hydrophobic Compounds!

The well-rounded, all-purpose core-shell Kinetex C18 HPLC column produces high efficiencies compared to traditional, fully porous columns. HPLC C18 columns come in various configurations to ensure outstanding performance and are recognized as the most retentive among alkyl-bonded phases. When used with UHPLC systems, the 2.6 µm size achieves similar performance to fully porous sub-2 µm particles but at significantly lower backpressure. Yielding remarkable chromatographic resolution, higher peak capacities, and greater sensitivity, the Kinetex C18 columns maximize the efficiency of every HPLC or UHPLC analysis.

Advantages of Kinetex Core-Shell C18 HPLC Columns

  • Compatible with all Analytical HPLC/UHPLC Systems*
  • Four fully scalable particle sizes available
  • Excellent Reproducibility and Batch-to-Batch Confidence
  • USP: L1

*Kinetex C18 analytical columns are compatible with all LC systems 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.

Compatibility

The Kinetex C18 column is fully compatible with all UHPLC instruments, ensuring seamless integration into any lab setup. This column is designed for easy installation and optimal performance. For installation, loosen the collet, place the tool between the gold compression screw and collet for quick release, adjust the tubing to the correct port depth, and connect the Kinetex column to the end-fitting. This universal compatibility allows you to leverage the powerful sub-2 µm column technology across different systems effortlessly.

Balances Retention and Performance 

The Kinetex C18 column offers a well-balanced C18 phase that delivers the highest level of hydrophobic selectivity compared to other Kinetex phases.
