摘要：

This paper reports the chromatographic performance of columns coated with 2,3,6-trimethyl-alpha-, beta-, and gamma-cyclodextrins (2,3,6-TriMe-alpha,-beta-, and gamma-CD) and their derivatives 2,6-dimethyl-3-trifluoroacetyl-alpha-, beta-, and gamma-cyclodextrins (2,6-DiMe-3-TFA-alpha-, beta-, and gamma-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.
