“…However, in the case of APCI, chemical equilibrium conditions can be attained, contrary to other ionization modes performed only under lowered pressures and non-equilibrium conditions. The main ion-molecule reactions in APCI, as for NCI with oxygen as reagent gas, are described as follows: The molecular ion for 2,3,7,8-TCDD cannot be obtained under APCI conditions with oxygen as reagent gas (Mitchum, Moler, & Korfmacher, 1980;Clement & Tosine, 1988). The detection limits for 2,3,7,8-TCDD/F in the SIM mode were 0.5 pg for the 2,3,7,8-TCDF standard (Clement & Tosine, 1988) and 14-40 pg in deionized water .…”

PCBs, chlorinated methoxybiphenyls, and some organochlorine pesticides did not interfere; therefore that method had an important advantage (Mitchum et al, 1982).…”

Reagent gases that are used in mass spectrometry in the NCI mode for the determination of polychlorinated dibenzo-p-dioxins (PCDDs), dibenzofurans (PCDFs), and biphenyls (PCBs) are discussed. Ion-molecule reactions and respective characteristic ions that form while using reagent gases (CH(4), O(2), i-C(4)H(10), NH(3), H(2), He, Ar, Xe, SF(6)) or gas mixtures (CH(4)/O(2), Ar/CH(4), CH(4)/H(2)O, Ar/O(2), i-C(4)H(10)/CH(2)Cl(2)/O(2)) are reviewed. It is shown that only CH(4), O(2), CH(4)/O(2), and CH(4)/N(2)O are widely used and well studied, even though-in the case of these reagent gases-there are contradictions between the publications of various authors. Such reagent gases as NH(3) and He are not well studied, but further investigations of their use for the determination of organochlorine pollutants could be of interest. The possibilities of more sensitive and selective determination of PCDDs, PCDFs, and PCBs are discussed.

“…Gas chromatography combined with high-resolution magnetic-sector-type mass spectrometry (GC/HRMS) has been employed to measure PCDD/Fs and related compounds. [1][2][3][4] However, the technique of selected ion monitoring (SIM) provides only a few chromatograms, thus reducing the reliability of assigning the analyte in real samples containing numerous interfering species. On the other hand, when samples derived from the environment are completely pretreated to measure a specific target molecule, information about other chemical species of interest is lost in the pretreatment process.…”

Polychlorinated Aromatic Hydrocarbons in a Soil Sample Measured Using Gas Chromatography/Multiphoton Ionization/Time-of-Flight Mass Spectrometry

Gas chromatography/multiphoton ionization/time-of-flight mass spectrometry (GC/MPI/TOF-MS) was applied to a soil sample to survey several groups of polychlorinated aromatic hydrocarbons (polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs), polychlorinated biphenyls (PCBs), polychlorinated naphthalenes (PCNs), polychlorinated diphenylethers (PCDEs), and polychlorinated terphenyls (PCTs)). The signal peaks in the two-dimensional display of GC/MS could be easily and accurately assigned from the intensity distribution of the isotope peaks, even in the presence of numerous interfering species. Using this technology, mutual interferences between organochlorine compounds can be readily recognized from the data of the two-dimensional display after a measurement, although the separation of these compounds is sometimes difficult using high-resolution magnetic-sector-type mass spectrometry. This approach, based on MPI, results in less fragmentation, and is useful for the identification of analytes. Thus, GC/MPI/TOF-MS allows for the simultaneous determination of PCDD/Fs and related compounds in real samples containing numerous interfering species.
