Luna CN HPLC Columns

Luna CN HPLC Columns

The Luna brand of columns and media is more than just a product line from Phenomenex. It is a pledge to provide you with the highest level of satisfaction for your chromatographic goals. The Luna CN has Nitrile groups bound to the silica surface which offer a unique polar selectivity under reversed phase or normal phase conditions.

  • Extensive line of rugged particle sizes
  • Easy method scalability from HPLC to preparative and bulk purification LC
  • CN Ultra pure, metal-free silica (99.99% purity) (USP:L10)

Proven Reproducibility

For carboxyl‚ carbonyl‚ and amine containing compounds‚ Luna CN columns offer a unique polar selectivity in reversed phase and normal phase modes. Luna CN columns provide sharp peaks and great reproducibility run-to-run‚ column-to-column and batch-tobatch. State of the art modification of the silca surface ensures improved resistance to bonded phase hydrolysis providing one of the most stable CN phases on the market. The result:
  • Excellent polar selectivity
  • Improved peak shapes
  • One of the most stable CN columns under reversed phase or normal phase conditions
  • pH stable from 1.5 to 7.0
