The gas chromatographic behaviour of nickel and zinc diethyldithiocarbamates was examined on various supports, mainly of the Chromaton and Chromosorb families, coated with polydimethylsiloxane nonpolar stationary phase. The coefficients of asymmetry, retention ratios and relative molar responses with respect to C28H58, and numbers of theoretical plates were determined. While poor results were obtained with Chromosorb G, Chromaton N Super appears to suit well to thedetermination.
