Witryna9 lut 2024 · According to the Definitions of terms relating to mass spectrometry (IUPAC Recommendations 2013), “Adduct ions are formed by the interaction of a precursor ion with one or more atoms or molecules to form an ion containing all the constituent atoms for the precursor ion as well as the additional atoms from the associated atoms or … WitrynaAboutTranscript. In the analytical technique of mass spectrometry, atoms or molecules are ionized using a high-energy electron beam and then separated based on their mass-to-charge ratios (m/z). The results are presented as a mass spectrum, which shows the relative abundances of the ions on the y-axis and their m/z ratios on the x-axis.
