Introduction Proton Transfer Reaction Mass Spectrometry (PTR-MS) is a powerful analytical technique that has gained significant attention in the field of food science. It allows for the rapid and non-destructive analysis of volatile organic compounds (VOCs) in various food samples. Read more…
Exploring Volatile Organic Compounds Related to Phthalates: Understanding their Health Concerns In the modern world, we are surrounded by countless substances, some of which harbor hidden dangers to human health. Among these are volatile organic compounds (VOCs) associated with phthalates, Read more…
Chemical and Physical Parameters of the analyte The molecular properties of a neutral molecule are important in proton transfer reaction mass spectrometry (PTR-MS) because they affect the probability of the molecule undergoing proton transfer. Gas-phase molecular properties, such as proton Read more…
Energetics: PTR-MS Drift-tube Conditions A commonly used ionization procedure in a classic PTR-MS instrument incorporates proton-transfer reactions, usually taking H3O+ as a proton donor. One of the biggest benefit of using H3O+ as promary reagent ion is that it does Read more…
Ion-molecule Collision Reactions in Gas-Phase In mass spectrometry, ion-molecule reactions refer to the chemical reactions that take place between charged ions and neutral molecules within the gas phase of the instrument. These reactions can occur either before or after the Read more…
