Photochemical Impacts from Resolving Isomers and Interference Biases in PTR-ToF-MS Measurements of Atmospheric VOCs

Xin Feng, Lirong Hui, Yi Chen, Penggang Zheng et autres

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 PTR-ToF-MS was deployed at a suburban site in Hong Kong …

Resolving Isomer and Interference Biases in PTR-ToF-MS Measurements of Atmospheric VOCs and Photochemical Impacts

Xin Feng, Lirong Hui, Yi Chen, Yi Chen et autres

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 isobaric interferences, fragmentation, and ionization byproducts. Here, a thermal desorption preconcentration gas chromatography (GC) coupled with Vocus PTR-ToF-MS was deployed at …
