Application Note: Improved Recoveries of Polycyclic Aromatic Hydrocarbons (PAHs) as Defined in EPA 550.1 and Simultaneous Removal of Humic Acids from Water Using Strata® PAH
11 April 2013

This application note describes the effective extraction of polycyclic aromatic hydrocarbon compounds (PAHs) from water samples while humic acids, which often interfere with chromatographic separation, are removed from the sample using a SPE sorbent, Strata® PAH. It was also found that Strata PAH provides consistent, high recoveries of all 16 analytes listed under EPA Method 550.1.
