ASMS 2013 Poster Note
The purpose of this work was to prove the concept that ambient fine particulate matter 2.5 microns in diameter (PM2.5) collected by a Thermo Scientific™ TEOM (tapered element oscillating microbalance) filter can be used to monitor ambient semi-volatile organic compounds (SVOCs). A workflow including sample preparation, gas chromatography-time of flight mass spectrometry (GC-TOFMS), and ultra-high performance liquid chromatography (UHPLC) Thermo Scientific™ Orbitrap™ mass spectrometer (UHPLC Orbitrap MS) analysis of SVOCs is described. Applying this workflow, TEOM filters collected from two urban sampling stations were analyzed for targeted polycyclic aromatic compounds (PAHs) and non-targeted polar SVOCs such as pesticides and pharmaceutically active compounds.
