Although the cyclodextrin based GC stationary phases have already been discussed, it is now necessary to consider them in the light of their use as LC stationary phases. The three basic cyclodextrins, a, b and g are also used in LC but they, or their derivatives are bonded to silica gel, particles, which are then packed into a column. The cyclodextrin structure is shown in a slightly different form a that given previously in figure 37.
