Proline Derivatization and Enantioresolution by Chiral GC

Results and Discussion. Chromatograms showing the GC analyses of the proline mixture are presented in Figures 1 and 2.An Astec CHIRALDEX ® G-TA, 2 which is a unique chiral GC column made using a trifluoroacetyl derivatized cyclodextrin, was used. The achiral derivatization did not affect the chiral center of the molecule, as evidenced by the presence of two peaks in the chromatograms.
