摘要: The possibility of simultaneous application an electron capture (ECD) and a flame ionization detector (FID) connected to glass capillary column for analyzing polynuclear aromatic hydrocarbons (PNA) has been investigated. ECD/FID ratio is determined 46 PNA compounds. ratios vary from 0.02 117 with relative standard deviations better than 20 percent 10 replicate analyses. results suggest that the method may be used obtaining additional evidence in identifying environmental samples. Impurities transformation products were identified by computerized gas chromatography/mass spectrometry. Quinones diones are responsible high EC-response some trace components standard. An shown particulates urban atmospheres.
