HPLC of Structural Isomer Using
Cyclodextrin–Poly(vinylamine)-Coated Silica Columns, Part
II: Retention Behavior and Separation
G. Crini and M. Morcellet
Different supports for high-performance liquid chromatography are prepared by using the coating technology. These supports are based on silica beads coated with a b-cyclodextrin-containing poly(vinylamine). Surface area, pore size distribution, and solid-state nuclear magnetic resonance are used for the characterization of these supports. The two different methods of preparation used lead to different arrangements of the polymer layers; hence, the supports have different mobility, rigidity, and accessibility of the cyclodextrin ring.
