“…There are many applications which require this knowledge including environmental [37,41,82], forensics [42] and food and flavors [83][84][85][86]. GC × GC is an ideal technique for non-targeted analysis because it has the capability of separating many of the analytes in complex matrices due to its structured chromatograms and high peak capacity.…”

“…These features are known as Classification and Scripting. Classifications can be used to define areas of the two dimensional chromatogram where compound classes occur, and Scripting provides the facility to use VBScript programming to establish rules for filtering spectral data to locate compounds with defined spectral properties (LECO Corporation, 2008;Pierce et al, 2008;Hilton et al, 2010). This is particularly useful in searching for compounds that contain either chlorine or bromine atoms.…”

a b s t r a c tThe disposal and dumping of toxic waste is a matter of growing concern in developing countries, including South Africa. Frequently these countries do not possess access to gas chromatography-high resolution mass spectrometry (GC-HRMS) for the determination of persistent organic pollutants (POPs). This publication describes an alternative approach to the investigation of toxic waste using comprehensive gas chromatography coupled to time of flight mass spectrometry (GC Â GC-TOFMS). The technology permits both comprehensive screening of toxic samples for numerous classes of organic pollutants and also quantitative analysis for the individual compounds. This paper describes the use of this technique by analysing samples obtained from a hazardous waste treatment facility in South Africa. After sampling and extraction the samples were analysed for polychlorinated dibenzo-p-dioxins (PCDDs), polychlorinated dibenzofurans (PCDFs) and four dioxin-like non-ortho substituted polychlorinated biphenyls (PCBs). The quantitative values, as well as detection limits, obtained using the GC Â GC-TOFMS methodology compares well with those obtained using GC-HRMS; the accepted benchmark technology for this analysis. Although GC Â GC-TOFMS is not a target compound analytical technique (as is GC-HRMS), it is possible to obtain information on numerous other classes of organic pollutants present in the samples in one analytical run. This is not possible with GC-HRMS. Several different column combinations have been investigated for handling very complex waste samples and suggestions are presented for the most suitable combination.

“…Few applications of GC×GC were shortly reported (Eganhouse et al, 2009;Matamoros et al, 2010a;Hilton et al, 2010) and will be discussed in the present chapter. Recently, GC×GC applications devoted to measurement of volatile and semivolatile organic compounds in air and aerosol were reviewed and discussed (Arsene et al, 2011, Hamilton, 2010.…”
