“…Plausible means to this end include appending or interdicting soil pyrolysis by oxidation, e.g., in the main heating chamber and/or in downstream after-treatment chambers and/or by adsorption of unwanted by-products on active carbon (for subsequent further decontamination). Also important are means for on-line detection of PAH and other unwanted by-products in the treatment reactor and in process effluent streams, e.g., using laser-induced fluorescence (LIF) [18,19]. In soil thermal decontamination as in all technologies the efficaciousness of these and other means of performance implementation and assessment must be evaluated at the largest scale of planned operation.…”

“…Samples are generally drawn from the flame through the orifice of a quartz microprobe and collected in the heated loop of a GC sampling valve (Kassem and Senkan, 1991). In the case of less volatile compounds, the place of the sampling loop in this process is taken by trapping in liquid impingers (Thijssen et al, 1994) or on filters or sorbents (Fuerst et al, 1989;Wornat et al, 1992), followed by solvent extraction (Thijssen et al, 1994;Wornat et al, 1992) or thermal desorption (Fuerst et al, 1989). With its ability to separate compounds and distinguish among species with the same molecular weight, GC/MS complements the molecular-beam mass spectrometry technique that has been used in recent organophosphorus flame structure studies (Korobeinichev et al, 1996;Werner and Cool, 1997).…”

The technique of gas chromatography/mass spectrometry preceded by trimethylsilyl derivatization has been applied to identify combustion byproducts from a premixed CH4/O2/N2 flame doped with dimethyl methylphosphonate, a simulant for organophosphorus chemical warfare agents. The following species or their derivatization products were detected: dimethyl methylphosphonate, methyl methyphosphonate, dimethyl phosphate, monomethyl phosphate, methylphosphonic acid, orthophosphoric acid, phosphorous acid, and phosphonic acid. Reference mass spectra are provided for three of these species. Tests indicate that mixtures of these species did not participate in interchange reactions during sampling and analysis. Remaining to be investigated are the fate of reactive compounds from the flame, the possibility of reactions other than interchange reactions, and the possibility of losses of stable compounds at various points in the sampling and analysis procedure.

Condensed phase and gas phase combustion emissions were monitored from an enclosed, axi-symmetric natural gas/toluene flame with gas chromatography/mass spectrometry, on-line mass spectrometry, and tunable diode laser absorption spectroscopy. The system was operated al global equivalence ratios (GER) from fuel-lean to fuel-rich. Toluene concentrations were monitored with the mass spectrometer, and used for the determination of destruction and removal efficiency (DRE) as a function of GER. The condensed phase data indicated that increases in the emissions of toxic compounds, such as polynuclear aromatic hydrocarbons, coincided with decreases in DRE. Products of incomplete combustion, carbon monoxide, methane. and acetylene were measured with tunable diode laser absorption spectroscopy and the results indicate that acetylene was a sensitive surrogate for both DRE and toxic emissions from the combustor.
