Description
Summary:The role of the chain-length and double bond position for the separation of positionally isomeric unsaturated fatty acid p-methoxyphenacyl esters by silver ion HPLC was evaluated. A clear effect of chain-length on retention was found, with k" decreasing when the number of carbon atoms in the chain increased. Thus, the resolution was affected both by the chain length and double bond position with the double bond position having the major impact. This allowed for the resolution of complex mixtures of fatty acids that differ in chain length and position of the double bonds by a single chromatographic run. Examples of such separation on model mixtures are presented.
