HPLC Column CN


GREEN MALL®CN columns offer a unique polar selectivity in RP and NP mode. They provide sharp peaks and
great reproducibility run-to-run, column-to-column, and batch-to-batch. The smooth silica allows for a more uniform
bonding with improved resistance to bonded phase hydrolysis to produce one of the most stable CN phases. The
high coverage combined with a thorough endcapping makes CN columns suitable for the separation of ionizable
compounds such as basic drugs, organic acids, and steroids as well as carboxyl, carbonyl, and amine containing
compounds.
 
Features of Green MALL® CN Columns

·     Monomerically bonded cyanopropyl group
·     Exceptionally high surface coverage and alternative selectivity
·     Low hydrophobicity for rapid elution of hydrophobic analytes
·     More reproducible separations than silica for NP applications
·     Multi-mode column (RP, NP, & HILIC) widens scope of selectivity
·     High retention capacity for polar and unsaturated compounds
·     Excellent reproducibility and superior stability
·     Quick equilibration and less sensitivity to small changes of the water content in the mobile phase
·     Suitable for the separation of ionizable compounds such as basic drugs, organic acids, and steroids
