COSMOSIL Phenyl and Cyano HPLC Columns
The COSMOSIL PE-MS columns (phenylethyl group) and the COSMOSIL CN-MS columns (cyanopropyl group) provide a secondary separation mode (π-π interaction). These columns are recommended when the other alkyl chain stationary phases do not offer optimum selectivity for structurally similar compounds.
