Useful chromatographic space is usually considered in terms of modifications to non-polar retention. This is understandable because the GC is useful for volatile compounds and that usually means organics. Organics that can be vaporized are generally high in non-polar (alkane or hydrocarbon) character. It is this part of their surface that allows them to be soluble in a non-polar phase. It is also this characteristic that makes the BP1 (dimethylsiloxane) a universal phase.
