Short summary
This study provides two methods for the quantification of molecular markers to improve the description of secondary organic aerosols using chromatographic techniques coupled with mass spectrometry. Compounds from various chemical functionalities (alcohols, acids, aldehydes), from biogenic and anthropogenic origin, were identified. Improved method performance was observed for nitro compounds, which have been associated with anthropogenic activities.
