Hi, I'm looking for a LC method for fractionation of oil components (SARA)

Question

I want to fractionate a crude oil into saturate, aromatic, NSO/asphaltene components and then recover the saturate and aromatic components for further chromatographic analysis.

Can anyone advise a suitable set up??

Thanks

Hi, 
 unfortunately this is not simple and that means very complicated, but there are plenty of articles about it: 
 
 Evaluating Crude Oils by SARA Analysis | SPE Improved Oil Recovery Conference | OnePetro 
 Determination of Saturate, Aromatic, Resin, and Asphaltenic (SARA) Components in Crude Oils by Means of Infrared and Near-Infrared Spectroscopy | Energy & Fuels (acs.org) 
 
 They might help.
