The COSMOSIL PE-MS, CN-MS columns (phenylethyl functional group) and the COSMOSIL CN-MS columns (cyanopropyl functional group) possess a secondary separation mode (p-p interaction). These columns are highly recommended for situations where a C18 or other alkyl chains cannot separate isomers and other compounds of structural similarity.

Analysis of mono-substituted benzenes
The COSMOSIL PE-MS shows slightly longer retention time for compounds such as nitrobenzenes, which have electron acceptors, or electron donor compounds (such as anisole). This suggests that COSMOSIL PE-MS may be effective for the analysis of the compounds, which cannot be separated by a C18 column.
Analysis of dinitrobenzenes
COSMOSIL PE-MS and COSMOSIL CN-MS separate those dinitrobenzene isomers which cannot be separated by C18 columns.
