Gas‐liquid chromatographic analyses of three complete series of synthetic positional isomers of methyl thia, selena, and tellura laurate analogs were carried on a nonpolar (SE‐30) and a polar (SP‐2330) stationary phase. The average ECL (equivalent chain length) values of the thia, selena, and tellura laurate on SE‐30 stationary phase were 13.8, 14,8, and 15.7, respectively, while on SP‐2330 the average values for the same series were 17.1, 19.0, and 19.1, respectively. Positional isomers with the heteroatom at the 2‐position exhibited the lowest ECL values, while those with the heteroatom at the ω‐1 position gave the highes ECL values and were readily separated from the other positional isomers of the same series of analogs by this technique.
