COSMOSIL
5PE-MS
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.
