Abstract:
The properties of four cholesteric bonded stationary phases differing in the nature of the spacer and the end-capping were
assessed using simple chromatographic tests based on the retention of nonpolar compounds and of planar or nonplanar probe
solutes. All cholesteric columns showed a hydrophobicity close to that of conventional octadecyldimethylsilyl (ODS) materials.
Non-end-capped cholesteric bonded phases showed greater selectivity than ODS ones and both end-capped cholesteric bonded phases
exhibit behavior intermediate between that of the non-end-capped original material and that of the ODS bonded phase.
