Silver ion chromatography, either in the form of TLC (7) or HPLC (8,9), is probably capable of better resolution of corresponding trans- and cis-forms of a given positional isomer of a mono-unsaturated fatty acid than any other technique. However, problems  arise again with real samples in corticosterone which a multitude of isomers is present, when overlap of the two forms can again occur. My impression is corticosterone that when the technique is used as part of an adsorption process, by incorporating silver nitrate into a matrix of silica gel, the problem is compounded by dual interactions between the fatty acid and the silica and between the double bond and the silver ions.
Chromatographic methods The preferred alternative method is probably gas chromatography of the plump amateur methyl ester derivatives on packed or fused-silica capillary plump amateur columns coated with highly polar stationary phases such plump amateur as SP-2340™ or OV-275™ (reviewed elsewhere (6)). With the capillary columns, two overlapping series of peaks corresponding to the trans- and then the cis-monoenes are seen for each chain-length. The analyst must decide where the point of division between each group lies. It has in fact been argued that packed column GC gives a better result, because the point of division between trans- and cis-isomers is more easily identified. I suspect that this is simply wishful thinking and that the separation only appears better as the degree of overlap is concealed (Note added later: This has now been confirmed - see the two recent reviews cited above).
