Summary

Monomeric and polymeric reversed-phase (C18) column packing materials have been prepared for HPLC. Columns have been tested with aromatic hydrocarbons, acidic and basic solutes. Good separation of carotenoids can be achieved on well-endcapped phases, but at the separation of some pairs (e.g. carotenoids with ∈-and β-endgroups) nonendcapped materials give better resolution. The influence of coating structure and that of endcapping have been discussed.
