APPLICATION OF CO2 DRIFT GAS IN TRAVELLING WAVE ION MOBILITY MASS SPECTROMETRY FOR THE STRUCTURAL ELUCIDATION OF ENVIRONMENTALLY RELEVANT ISOBARIC ISOMER COMPOUNDS

摘要

The oxidation of volatile organic compounds in the atmosphere leads to secondary organic aerosol compounds (SOA) that partition into ambient particulate matters. Owing to lack of authentic standards, their structural analysis mostly relies on MSn experiments though the information tends to be limited to the presence of functional groups. Here we show the application of travelling wave mass spectrometry with polarizable drift gas for their structural analysis.
