The
application of the linear solvent energy relationships method to the
characterisation of hyper cross-linked polystyrene stationary phases
Abstract
The possibility of using the Linear Solvent Energy
Relationships theory for the characterisation of hyper cross-linked polystyrene
HPLC stationary phases was investigated. Studying the LSER coefficients it was
shown that the major contribution into the retention of analytes on the HCLP is
given by hydrophobic and electrostatic interactions. It was shown that
modification of the stationary phase with fluorine increases both hydrophobic
and electrostatic interactions in the retention mechanism. The possibility of
using fluorinated hyper cross-linked polystyrene for the separation of
alkylbenzenes and di-alkylphthalates mixtures was shown.
