Unveiling the Veil of Volatile Organic Compounds: Cork Taint in Wine and Beverages Wine connoisseurs savor the intricate flavors and aromas that dance on their palate with each sip. Yet, amidst the symphony of sensations, there lies a potential spoiler Read more…
Volatile Organic Compounds (VOCs) in Food Packaging Food packaging plays a crucial role in preserving food quality, extending shelf life, and preventing contamination. However, certain types of packaging materials can release volatile organic compounds (VOCs) into the food they contain. 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…
