| Abstract
| - The use of “Durapaks” OPN/Porasil, and Carbowax 400/Porasil, in which the liquid phase is permanently bonded to the core material, to separate mixtures of methyl esters of short and long chain saturated fatty acids and fatty aldehydes is illustrated. A partial separation of the methyl esters of the C18 saturated and unsaturated fatty acids occurred on the OPN column. The permanently bonded“Durapak” column packings are suitable for GLC analysis of some lipids since they obviate the necessity for long periods of column conditioning due to bleeding phenomena usually associated with substrate-loaded packings.
