Identification of PCB's in the presence of DDT-type compounds using low temperature luminescence.
Low temperature (77 degrees K) luminescence spectra of polychlorinated biphenyls (PCB's), DDT-type compounds and mixtures suggest a simplified method for identification and quantitation of aromatic pesticides with minimal prior sample treatment. Spectral differences allow identification of PCB's in the presence of DDT and the converse. Approximate detection limits, possible interferences and suggestions for further work are discussed
