“…[15][16][17] In the present study, REMPI-TOFMS was combined with gas chromatography (GC) for the trace analysis of 16 PAHs on the priority list of the U.S. EPA. We employed a small-frame, low-cost nanosecond laser emitting at 266 nm for the practical trace analysis of PAHs.…”

“…An analytical instrument for GC/MPI/TOF-MS has been reported in detail elsewhere, 13 and is only briefly described here. One microliter of sample solution was injected into a GC (Agilent Technologies Inc., 6890N, Little Falls, DE) using a pulsed-splitless mode.…”

“…In particular, it could be visually ascertained that the concentration of pentaCNs should be carefully determined when intense tetraCB peaks, e.g., 3,3′,4,4′-tetraCB, are observed. Care should be taken, not only for intense 12 C-native tetraCB, but also 13 C-labeled tetraCB that may have been added as an internal standard. The molecular weight of [M] + for 13 C-labeled tetraCBs (m/z = 301.9626) is very close to that of [M+4] + for pentaCNs (m/z = 301.8618).…”

“…Isomers with zero TEF values were employed in order to avoid contamination of the equipment and the laboratory. The internal standard of 13 C-labeled 1,2,3,4,6-pentaCDF (Wellington Laboratories) was added to the sample mixture, and was prepared at a concentration of 10 pg/μL. A soil sample derived from an industrial waste yard in Fukuoka, Japan was a gift from Fukuoka Institute of Health and Environmental Sciences.…”

“…[9][10][11][12] In previous reports, pentachlorodibenzofurans (pentaCDFs) were differentiated from interfering species using a technique of two-dimensional display derived from a soil sample. 13,14 In the present study, GC/MPI/TOF-MS was utilized in the analysis of organochlorine compounds extracted from a soil sample, to demonstrate the advantages of this method over GC/HRMS. Accelerated solvent extraction (ASE), 15 adopted in U.S. Environmental Protection Agency (EPA) method 3545A, 16 was employed in the process of pretreatment of the soil sample.…”

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.

Chlorine–fluorine exchange in XeF+ leads to the orange crystalline salt [XeCl]+[Sb2F11]− (see structure), which is stable below −10°C. Thus, the number of known noble gas monohalogen cations is now three and, as calculations show, is approaching the theoretically possible limit. The synthesis of other such compounds—with the exception of ArF+, which remains a formidable task—seems unlikely.
