Summary In most capillary GCL columns the film thickness is almost always the same. In addition to column dimensions, liquid phase and support characteristics, however, the film thickness of a column is of great importance and should be adjusted for the specific problem. Dependence of retention, separation efficiency, inertness, capacity, and thermal stability on film thickness is empirically shown for a 100-fold (1∶100) thickness range. In conclusion, directions are given for determining the appropriate film thickness for the different types of sample and analytical tasks.
