Photochemical Impactsfrom Resolving Isomers and InterferenceBiases in PTR-ToF-MS Measurements of Atmospheric VOCs

Abstract While proton-transfer-reaction time-of-flight mass spectrometry (PTR-ToF-MS) is widely used for ambient volatile organic compounds (VOCs) quantification, its accuracy is limited by isomeric speciation and ionization byproducts. Here, gas chromatography (GC) coupled with...
