Gas chromatographic resolution of  polyunsaturated wax esters based on their degree of unsaturation on Silar 10C.
Wax esters of C28-C44 chain-lengths, and containing 0-7 double bonds, were characterized with equivalent chain lengths [ECL] obtained by GC using a cyanosiloxane, Silar 10C. The ECL of the unsaturated wax esters is significantly dependent upon the column temperature, and selection of an appropriate column temperature permitted adequate resolution of critical pairs differing in the degree of unsaturation or the position of the double bonds.
