Abstract

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.

Cyclodextrin derivatives (CDDs) are successful GC enantioselective stationary phases to evaluate essential oils through the enantiomeric composition of their optically active components. The most recent CDDs have greatly enlarged the number of separable racemates and, in many cases, it is now possib

## Abstract As a continuation of previous studies on the use of cyclodextrin derivatives (CD) for the separation of volatile compounds by capillary GC, the influence of diluting phases other than OV‐1701 or OV‐1701‐OH has been investigated. 2,6‐Di‐__O__‐methyl‐3‐__O__‐pentyl‐β‐cyclodextrin (2,6‐Di
