Is there reversed phase media for unpolar mobile phases?

In order to get another solution for LC, I would try to separate lipids on RP's, but these are still soluble in very unpolar solvents. So are there any reversed phases which are stable against more unpolar mobile phases similar to a gradient like Hexane/iso-Propanole/Water (0/80/20 to 80/20/0 in 15 min) or Chloroform/Methanol (80/20) isocratic?
