Published in 2025 at "Frontiers in Ecology and Evolution"

DOI: 10.3389/fevo.2025.1536032

Abstract: Proton Transfer Reaction Time-of-Flight Mass Spectrometry (PTR-TOF-MS) provides high-resolution, real-time tracking of volatile organic compounds (VOCs), yet its analytical workflows for complex mixtures are often underexplored. This study presents a flexible data analysis workflow tailored… read more here.

Published in 2024 at "Atmospheric Measurement Techniques"

DOI: 10.5194/amt-17-801-2024

Abstract: Abstract. Proton-transfer-reaction time-of-flight mass spectrometry (PTR-ToF-MS) is a technique commonly used to measure ambient volatile organic compounds (VOCs) in urban, rural, and remote environments. PTR-ToF-MS is known to produce artifacts from ion fragmentation, which complicates… read more here.
