However,
among them only one example of EEO reversal based only
on the polymer backbone was observed between Lux Cellulose-
1 and ADMPC-based chiral columns in ACN as the
mobile phase (Fig. 5). Since in this case, the pendant groups
on the phenyl moiety of these two chiral selectors, as well
as their elemental composition is the same, it is obvious that
the structure of the chiral polymer affects its affinity pattern
for the enantiomers of carprofen. It seems worth mentioning
that more reversals of EEO were observed in ACN compared
to alcohol-type mobile phases.
