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‐_
## Abstract This paper describes an evaluation of the chromatographic performance of columns coated with amorphous cyclodextrin (CD) derivatives, in particular 2,3,6‐tripentyl‐β‐CD (2,3,6‐TriPe‐β‐CD), 2,6‐dipentyl‐3‐methyl‐β‐CD (2,6‐DiPe‐3‐Me‐β‐CD), and 2,6‐dimethyl‐3‐pentyl‐β‐CD (2,6‐DiMe‐3‐Pe‐β‐C
