Abstract

Chlorinated organic compounds react with the brass-nozzle of the dc-plasma jet. The products generated (of the type CuClx) cause an emission signal for copper equivalent to the content of chlorine. An analogous signal can be observed for organic substances containing bromine or iodine; a signal does not appear for fluorinated substances. This modified Beilstein principle may be used for the determination of small amounts of chlorinated organic substances by optical emission spectrometry after pre-separation by gas-chromatography.
