Abstract:

Samples of egg and soybean phosphatidylcholines were fractionated by total number of double bonds on silver ion-saturated resin columns using solvent programming (acetonitrile in methanol). Stainless-steel columns were packed with 15-microns resin which had been isolated by air elutriation. Methods of column packing, silver ion incorporation, solvent-resin interactions and resin regeneration are also discussed.
