T. HORÁK, J. ČULÍK, M. JURKOVÁ, V. KELLNER

The method which enables to determine eleven aliphatic chlorocarbons (dichloromethane, 1,1-dichloroethane, 1,2-dichloroethane, trichloromethane, 1,1,1-trichloroethane, 1,1,2-trichloroethane, trichloroethylene, tetrachloroethylene, tetrachloromethane, 1,1,1,2-tetrachloroethane a 1,1,2,2-tetrachloroethane) by means of headspace technique combined with gas chromatography has been developed. The work deals with the determination of optimal conditions for headspace technique so in other that analysis itself was rapid, simple and at the same time results complied with legislative regulations given by the notice MH CR No.298/1997 Dig. The attention is given even to influencing of results by different type of matrix (beer) and to preparing of standard. The work involves separation conditions by means of the technique of gas chromatography with electron capture detector and validative characteristics of the optimized method for all determined substances. The illustrated chromatogram is attached.
