A multifunctional test mixture for chiral cyclodextrin GC columns

Gas chromatography (GC) is a powerful tool in the separation science of chiral analytes. The development of a new chiral test mixture for cyclodextrin (CD) coated GC columns allows comparing, choosing and identifying most suitable columns for a given separation challenge. This test mixture contains 12 enantiomer pairs of a broad range of functional groups and it is the first mixture suitable for all types of modified cyclodextrin capillary columns. Column changes can be observed and system performance can be monitored by means of this test mixture, which is therefore a base for reliable results. Furthermore, this publication is thought to be a start-up aid for chiral GC.
