Abstract:
Polycyclic aromatic hydrocarbons (PAHs) were determined in a petroleum vacuum distillation residue using the Agilent Multiple Heart-Cutting (MHC) 2D-LC solution. The extract was analyzed in the first dimension by normal-phase LC. Well-defi ned fractions from this separation were stored in a set of sample loops, then transferred online to the second-dimension separation where the PAHs were separated from each other and from other sample constituents using reversed-phase LC on a dedicated PAH column. Detection was performed with diode-array detection (DAD) as the monitor detector after the fi rst dimension, and with fluorescence detection (FLD) after the second dimension. An additional column switching valve enabled backflush of the first-dimension normal-phase column to remove highly polar components. The Agilent 1290 Infinity 2D-LC solution enabled automated, selective, and quantitative analysis of the PAHs in the complex petroleum vacuum distillation residue sample.
