Dimethyl disulfide (DMDS) adducts are prepared from fatty acid methyl esters to locate the double‐bond position in monoenoic fatty acids by gas chromatography/mass spectrometry. We improved our original procedure for preparing DMDS adducts with a simple device that can be made in any laboratory using a glass pipette and silica based packing material, Extelut NT.
