Short summary
A novel non-destructive, sulfuric-acid-free clean-up method for high-volume air samples was developed and evaluated with organic chemicals covering a wide range of polarities (logP 2–11). This method, providing quantitative results of comparable quality to traditional methods, was combined with newly developed data treatment strategies for simultaneous suspect and non-target screening. The application to air samples from southern Norway revealed 90 new potential chemicals of emerging concern.
