Kinetex Core-Shell Technology Columns
The Core-Shell Advantage

Kinetex Core-Shell Technology delivers dramatic improvements in efficiency over conventional fully porous media which can be leveraged to increase resolution, greatly improve productivity, reduce solvent consumption, and decrease costs. Whether you are running HPLC or UHPLC methods, the Kinetex core-shell family can deliver shockingly improved performance over the current column you are using. Phenomenex designs, manufactures, and sells its very own silica and organo-silica core-shell particles. The combination of a consistent, solid high density core along with proprietary column packing technologies ensures optimum bed structure and high column performance.

  • Performance gains on ANY LC system
  • System-to-system and lab-to-lab method portability
  • Improve the productivity of older, established methods

Kinetex Core-Shell Technology Columns
Kinetex Core-Shell Performance on Any LC System
Using sol-gel processing techniques that incorporate nano-structuring technology, a durable, homogeneous porous shell is grown on a solid silica core to create a Kinetex Core-Shell particle. This particle morphology results in less band broadening for all four sources of UHPLC band broadening compared to fully porous particles and thus delivers extremely high efficiencies.
Optimized for Ultra-High Performance

Core-Shell Performance Gains

Kinetex Core Shell Technology finely tuned and unique core shell manufacturing process delivers dramatic improvements in efficiency over conventional fully porous media which can be leveraged to increase resolution, greatly improve productivity, reduce solvent consumption, and decrease costs Whether you are running HPLC or UHPLC methods, the Kinetex core shell family can deliver shockingly improved performance over the current column you are using.

Kinetex Polar C18

Fully Porous

High Efficiency‚ High Density Particle

Kinetex particles are built with a solid high density core that promotes the particles to settle into an optimal bed structure. This reduces the band broadening effects of Eddy Diffusion since the interstitial space between the particles is virtually homogeneous and results in ultra-high column efficiency and excellent reproducibility.

Achieve Sub-2 µm Performance within HPLC Backpressure Limitations

With the efficiency of a sub-2 µm column and typical operating backpressure less than 400 bar‚ you can achieve the promise of ultra-high performance on any LC system.

† Kinetex 2.6 μm columns‚ 2.1 mm ID‚ are pressure rated to 1000 bar use on both HPLC and UHPLC instrumentation.

Polar Acidic Compounds 
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 runtime, increase sensitivity, and even provide greater resolution with much higher efficiency levels. 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.
