Determination of highly polar compounds in atmospheric aerosol particles at ultra‐trace levels using ion chromatography Orbitrap mass spectrometry
Abstract A method using ion chromatography coupled to high‐resolution Orbitrap mass spectrometry was developed to quantify highly‐polar organic compounds in aqueous filter extracts of atmospheric particles. In total, 43 compounds, including short‐chain carboxylic acids, terpene‐derived acids, organo...
