As a result of a greater understanding of the chiral recognition mechanism, an ever increasing number of chiral analytes can be separated by both GC and LC. In 1991, Astec received two global patents for the use of two specific cyclodextrin derivatives for the separation of enantiomers by capillary GC. This
