Jojoba Oil - Has anyone successfully removed Fatty Alcohols from Fatty Acids prior to BF3 in FAME reaction?

Working in small volumes - Jojoba oil breaks into free fatty acids and fatty alcohols after the -OH reaction.  The fatty alcohols remain through the process untouched and end up in the chromatography.  How can you remove the fatty alcohols so that you only see the fatty acid profile.
