Polycyclic aromatic hydrocarbons (PAHs) and their halogenated derivatives (XPAHs) are ubiquitous in various environmental media. Anal. problems, however, make it difficult to accurately determine their concentrations To develop a satisfactory anal. method suitable for a diversity of PAHs and XPAHs in multiple environmental samples, we evaluated three com. anal. columns (DB-5MS, Select PAH, and Rxi-PAH) for better chromatog. separation and optimized the anal. conditions for gas chromatog.-triple quadrupole mass spectrometry (GC-MS/MS). Comparison of the abilities of the columns to sep. peaks revealed that the Rxi-PAH was the best column for both PAH and XPAH analyses. Optimization of anal. conditions for GC-MS/MS resulted in sensitivities for PAHs and XPAHs that were 4.2-fold-2600-fold higher than the sensitivities of GC-high-resolution MS (GC-HRMS) (an example of a traditional anal. method). Although there were no statistically significant differences between the instrumental detection limits (IDLs) of PAHs and XPAHs measured by GC-HRMS, the IDLs of XPAHs were significantly lower than those of PAHs when measured by GC-MS/MS. This difference could be attributed to the unique ionization patterns of XPAHs in the GC-MS/MS anal., which suppressed background noise and increased the anal. sensitivity. Analyses of PAHs and XPAHs in grilled chicken, vehicle exhaust, sea sediment, ambient air, and indoor dust via the anal. method optimized in this study revealed that the proposed method was sufficiently sensitive, comprehensive, and versatile for risk assessment purposes, and could eliminate interferences associated with the co-elution of target PAHs and XPAHs. In the experimental materials used by the author, we found 9,10-Dibromoanthracene(cas: 523-27-3Quality Control of 9,10-Dibromoanthracene)
9,10-Dibromoanthracene(cas: 523-27-3) is a dibrominated polycyclic aromatic hydrocarbon (PAH). 9,10-Dibromoanthracene is often used as an energy acceptor and activator in reactions that produce chemiluminescence.Quality Control of 9,10-Dibromoanthracene
