摘要：
Relative polarity values and retention indices for a mixture of normal paraffins C-5-C-10 and alkylbezenes C-6-C-9 are determined for four types of monolithic capillary columns based on divinylbenzene, ethylene glycol dimethacrylate, pentaerythritol tetraacrylate, and pentaerythritol triacrylate. It is established that the retention of polar sorbates increases with a rise in stationary phase polarity, while the retention of nonpolar compounds grows with a reduction in stationary phase polarity.
