    J Chromatogr A 1186:202-10. 2008
    ..5 to 50 ng/mL concentrations of numerous organochlorine and organophosphorus pesticides were used to demonstrate linearity and the GC x GC benefit of eliminating interferences that might contribute to quantification bias...

    Restek Corporation, Middelburg, The Netherlands
    J Sep Sci 32:1849-57. 2009
    ..Activity plays a minimal role, and also leaks will not be an issue as the coupling is in 100% inert gas. Data obtained using this concept is promising as vacuum GC becomes easier and more robust...

    Environ Sci Technol 36:4346-51. 2002
    ..In addition, pyrolysis successfully identified the AA2 components capable of surviving the incineration process intact. This work illustrates the potential of bench-scale pyrolysis for predicting incineration behavior...
