[Gas-chromatographic determination of insecticidal chlorinated hydrocarbons using the GCHF 18.3-6 gas chromatograph with an attached electron detector].

The authors describe the gas chromatographic determination of residues of insecticidal chlorinated hydrocarbons in foods by means of the GCHF 18.3-6 gas chromatograph with electron attachment detector of the VEB Chromatron Berlin which is most frequently available in the GDR for routine work. Furthermore, the authors deal with possibilities of identifying and confirming residues of chlorinated hydrocarbons with the aid of chemical reactions.
