Identification of the major polyunsaturated C₁₆ acids of marine oils by GLC separation factors on normal and organosilicone polyesters

The tentative identification of the unsaturated C 16 acids of marine oils is facilitated through analysis on both normal and organosilicone polyester substrates. Two different separation factors can then be approximated from the more accessible separation factors appropriate to unsaturated acids of longer chain lengths.
