摘要：
The separation of diastereoisomers from oligomers of low molecular weight polystyrene was achieved using a carbon clad zirconia stationary phase and an acetonitrile mobile phase. The selectivity of the C18 - methanol system separated the polystyrene oligomers based on molecular weight while the carbon clad zirconia surface in combination with an acetonitrile mobile phase allowed the expression of the isomeric sample dimensionality. Consequently, full utilisation of the different retention mechanisms on each surface greatly improved the isomeric separation from oligomers of low molecular weight polystyrene.
