Summary

The gas Chromatographic behaviour of some metal di(trifluoro-ethyl)- and di-isobutyldithiocarbamate chelates on short glass and fused-silica capillary columns was investigated. The Kováts retention indices were determined. The zinc chelates were found to be highly susceptible to decomposition. Some of the metal di-isobutyldithiocarbamate chelates showed slight tailing at low concentrations, indicating slight interaction with the liquid phase. The degree of tailing was measured by means of a tailing index.

Zusammenfassung

Das gaschromatographische Verhalten einiger Metallkomplexe mit Ditrifluoroethyl bzw. Di-isobutyldithiocarbamat in kurzen Kapillarsäulen aus Glas bzw. Quarz wurde untersucht. Die Kováts-Retentionsindices wurden bestimmt. Die Zinkchelate erwiesen sich als sehr unbeständig. Einige Metall-di-isobutyldithiocarbamate zeigten leichte Schwanzbildung bei geringen Konzentrationen infolge des Einflusses der flüssigen Phase. Deren Ausmaß wurde mit Hilfe des Tailing-Index gemessen.
