Proton-transfer-reaction mass spectrometry (PTR-MS) is a highly sensitive and selective analytical technique used primarily for the real-time detection and quantification of volatile organic compounds (VOCs) in gas phase samples. The method is particularly valuable in fields such as environmental monitoring, atmospheric chemistry, and biomedical applications.
