Cyclodextrin derivatives in GC separation of racemic mixtures of volatiles – part XII: Thick‐film wide‐bore columns for enantiomer GC preparation

Preliminary results on thick‐film wide‐bore (0.53mm i.d.) columns for GC preparation of pure enantiomers are described. In particular the loading capacity for several racemates of a 3μm, 30% 2,6‐di‐ O ‐methyl‐3‐ O ‐Pentyl‐β‐CD/OV1701 column and of a 2 μm, 30% 2,3‐di‐ O ‐acetyl‐6‐ O ‐dimethyl‐t‐butylyl‐β‐CD/PS‐086 collumn were determined. Consideration is also given to the relation‐ship between resolution values of two enantiomers on anayltical columns and their loading capacity and scaling‐up to the corresponding micropreparative columns.
