Abstract

This paper reports the chromatographic performance of columns coated with 2,3,6‐trimethyl‐α‐, β‐, and γ‐cyclodextrins (2,3,6‐TriMe‐α,‐ β‐, and γ‐CD) and their derivatives 2,6‐dimethyl‐3‐trifluoroacetyl‐α‐, β‐, and γ‐cyclodextrins (2,6‐DiMe‐3‐TFA‐α‐, β‐, and γ‐CD), all six diluted in polysiloxane, for the separation of the enantiomers of volatile compounds.

The influence of column length and film thickness on separation is reported. Phenomena related to reproducibility and consistency, over a period of time, of columns prepared with these CD derivatives are also discussed, and a possible solution to some drawbacks reported here is proposed.

The chromatographic separation of racemic mixtures of volatile compounds by 2,3,6-trimethyl-a-, fland y-cyclodextrins is discussed. Columns were prepared by mixing the derivatized cyclodextrin with OV-1701 or hydroxy-terminated OV-1701 (OV-1701-OH) following Schurig's method [l]. About 130 racemates

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 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‐_
