Investigation of ultrahigh‐performance liquid chromatography/travelling‐wave ion mobility/time‐of‐flight mass spectrometry for fast profiling of fatty acids in the high Arctic sea surface microlayer
Rationale Fatty acids are enriched in the ocean surface microlayer (SML) and have as a consequence been detected worldwide in sea spray aerosols. In searching for a relationship between the properties of the atmospheric aerosol and its ability to form cloud condensation nuclei and to promote cloud d...

Conclusions This study presents a fast alternative method for screening and profiling of FAs, which has the advantage of not requiring any complicated sample preparation, thus limiting the loss of analytes. Almost no manual handling, together with the very small sample volumes needed, is certainly beneficial for the determination of trace amounts and should open up the field of applications to also include atmospheric aerosol and fog.
