A capillary gas chromatographic column with Nafion film as stationary phase was prepared via a verified dynamic coating procedure.The separation performance of the Nafion film coated capillary column was studied with linear alkanes
linear alcohol
pinene isomer and aromatic isomer
and its morphology was analyzed by SEM.Results showed that the column could offer effective separations for linear alkanes
terpene isomer as well as aromatic positional isomer.Effect of temperature on separation of terpene isomer and aromatic positional isomer was investigated
which was used to elucidate that the separation process for aromatic positional isomer was controlled by both entropy and enthalpy
but the separation process for terpene isomer was controlled only by enthalpy.
