C. Bicchi et al., CYCLODEXTRIN DERIVATIVES IN GC SEPARATION OF RACEMIC MIXTURES OF VOLATILES .12. THICK-FILM WIDE-BORE COLUMNS FOR ENANTIOMER GC PREPARATION, HRC. Journal of high resolution chromatography, 20(9), 1997, pp. 493-498
Preliminary results on thick-film wide-bore (0.53 mm i.d.) columns for
GC preparation of pure enantiomers are described. In particular the l
oading capacity for several racemates of a 3 mu m, 30% 2,6-di-O-methyl
-3-O-pentyl-beta-CD/OV1701 column and of a 2 mu m, 30% -O-acetyl-6-O-d
imethyl-t-butylsilyl-beta-CD/PS-086 column were determined. Considerat
ion is also given to the relationship between resolution values of two
enantiomers on analytical columns and their loading capacity and scal
ing-up to the corresponding micropreparative columns.
