Dear All,
Any help is appreciated:
I am dissolving my non-polar matrix (including aldehydes and alcohols) in hexane (1ml in 10ml hexane). This I pass through the column. My aldehydes and alcohols are retained (some hexane and non-polar matrix is left too). When I try to remove residual non-polar matrix with hexane, the aldehydes elute from the column (the alcohols remain retained). I am not concerned about residual hexane in the final eluate (with ethyl acetate) but I want the aldehydes in there too and not much non-polar matrix.
Regards
WK
