ABSTRACT
The possibility of applying inexpensive CHROMA 2001 system for identification and quantification of selected organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) in multicomponent food extracts was studied (fish, human milk). Chromatographic separation (GC-ECD) of the examined analytes was carried out on a ZB-5 capillary column (60 m; 0.25 mm i.d.; film thickness 0.25 μm). Two methods of the data acquisition and processing were created. Each analyte was identified by a comparison of the retention times (RTs) and relative retention times (RRT53 or RRT30+209) of the peaks from calibration standards with peaks from cleaned-up extracts. In quantification, a one-point calibration curve method was used. The results obtained indicate that the use of automatic data processing of multicomponent chromatograms by Chroma 2001 is limited. During identification of more than 14 analytes, manual data processing is required. Nevertheless, the application of CHROMA 2001 reduces considerably the time necessary for qualitative and quantitative GC analysis of multicomponent food extracts.
