J. Hrouzek et al., Detection limit of Ni(II)bis[di(2,2,2-trifluoroethyl)dithiocarbamate] determined by gas chromatography with electron capture detector, CHEM PAP-CH, 52(5), 1998, pp. 662-666
Capillary gas chromatography with electron capture detector was used for th
e determination of a detection limit of Ni(II)bis[di(2,2,2-trifluoroethyl)
dithiocarbamate] (Ni(TFDEDTC)(2)) in hexane solutions. The given chelate wa
s prepared by the reaction of Ni ions in aqueous samples with sodium(2,2,2-
trifluoroethyl)dithiocarbamate and extracted to hexane. Under given chromat
ographic conditions 10 pg of Ni(TFDEDTC)(2) was detected with a relatively
high reliability at signal to noise ratio S/N = 3.
