Abstract
Analysis of pesticides and polychlorinated biphenyls in food matrices was provided by the method of complete two-dimensional gas chromatography/time-of-flight mass spectrometry. It was shown, that using of technology GC/GC is significantly improves separation of target compounds and decrease the limits of quantification in comparison with the common “one-dimensional” chromatography. Also, the study describes briefly the use of rapid separation for the analysis of trace contamination in food samples. High-speed temperature program, coupled with the possibility of deconvolution of spectra, using the TOF-type detector with the appropriate software, significantly reduces the total time of analysis compared with traditional methods.
