Liquid chromatography hplc column empty

Product Description

CN columns are based on our proprietary bonding and end-capping techniques to ensure excellent sharp peaks and reproducibility for the analysis of basic compounds. Due to stable bonding chemistry and excellent surface coverage, the columns exhibit exceptional stability at low pH compared to other cyano phases.CN columns offer unique selectivity due to dipole-dipole and dipole-induced dipole interactions, which are very useful for separation of a wide range of pharmaceuticals and peptides. They show excellent peak shapes for basic compounds and are a good first choice for compounds typically considered difficult to analyze.

Features

1. Low hydrophobicity, for rapid elution of hydrophobic molecules

2. Can be used in both Reverse Phase and Normal Phase analysis

3 .Unique selectivity for polar compounds

4. Retention and separation of strongly basic analytes, including quaternary ammonium salts, with excellent peak shapes

5. Compatibility with highly aqueous mobile phases

6. Exceptional batch-to-batch and column-to-column reproducibility.

7. Exceptional stability and column lifetime, from pH 1.5 to 9

8. Available in dimensions from analytical to preparative for all sample sizes
