Atomic Force Microscopy Identifying Fuel Pyrolysis Products and Directing the Synthesis of Analytical Standards.

摘要: Here we present a new method that integrates atomic force microscopy (AFM) with analytical tools such as high-performance liquid chromatography (HPLC) diode-array ultraviolet–visible (UV) absorbance, and mass spectrometry (MS) along synthetic chemistry. This allows the detection, identification, quantification of novel polycyclic aromatic hydrocarbons (PAH) in complex molecular mixtures. multidisciplinary methodology is employed to characterize supercritical pyrolysis products n-decane, model fuel. The experiments result mixture both unsubstituted well highly methylated PAH. We demonstrate AFM-driven discovery compound, benz[l]indeno[1,2,3-cd]pyrene, chemical structure assignment serving input for synthesis molecule. verified by AFM, synthesized compound used reference standard measurements, establishing first-ever unequivocal identification qua...
