Optimization of programmed temperature GC

It can be seen in table 6.3 that the optimization of selectivity in programmed temperature GC involves variation of the (nature or composition) of the stationary phase. To vary this parameter, a different column and re-optimization of the (primary) program parameters will be required. This is clearly not a very attractive proposition and therefore the optimization of programmed temperature GC is usually restricted to optimizing the program. 

If many peaks occur in a chromatogram this appears to be a very difficult proposition. However, the requirement of solute recognition may not give rise to insurmountable problems in the optimization of programmed temperature GC for the following two reasons ...
