摘要: Nitro-aromatic compounds are associated with a host of adverse human health and ecological outcomes; however, current methods detection limited by the lack accuracy for nontargeted identification nitro compounds. This paper describes development novel, accurate, selective method identifying compounds, especially polycyclic aromatic hydrocarbons (PAHs), in complex soot mixtures. For first time, high-performance liquid chromatography was used combination Orbitrap mass spectrometry validated on mixture 84 standard molecules containing 23 then applied to sample, National Institute Standards Technology reference material (SRM) 1650a, successfully identify 105 masses, 62% which were monosubstituted All reported latest certificate analysis (COA) SRM 1650b id...
