Abstract: Capillary gas chromatography with electron capture detector was used for the determination of a detection limit of Ni(II)bis[di(2,2,2-trifluoroethyl) dithiocarbamate] (Ni(TFDEDTC)2) in hexane solutions. The given chelate was prepared by the reaction of Ni ions in aqueous samples with sodium(2,2,2-trifluoroethyl)dithiocarbamate and extracted to hexane. Under given chromatographic conditions 10 pg of Ni(TFDEDTC)2 was detected with a relatively high reliability at signal to noise ratio S/N = 3.
