Long Column Lifetimes and Excellent Performance
Ultra-pure, metal-free silica (99.99 % purity) is the back bone of all Luna material. The resulting high quality particles have a surface smoothness, pore structure, and pore consistency to ensure a more uniform particle shape and greater reproducibility.

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
