Lopez-Avila et al. [170] used a stable isotope dilution gas chromatography-mass spectrometry technique to determine down to 0.1 ppb of pentachlorophenol (also atrazine, diazinon and lindane) in soil. Soil samples are extracted with acetone and hexane. Analysis is performed by high-resolution gas chro-matography-mass spectrometry with the mass spectrometer operated in the selected ion monitoring mode. An accuracy greater than 86% and a precision of better than 8% were demonstrated by use of spiked samples. 

PCB materials in field-collected bald eagle specimens have been identified utilizing combined gas chromatography-mass spectrometry techniques in conjunction with thin-layer chromatographic separations of standard materials as well as tissue extracts (26). A total of 19 PCB compounds were detected in the field samples. Analyses were performed employing a spiral glass gas chromatographic column, 9 ft X 0.25 inch o.d., packed with 1% SE-30 on 100/120 mesh Gas Chrom Q. Mass spectra of the major components of Aroclor 1254 PCB standard were presented in this report as well as relative retention data for the individual components.
