14 cze 2024 · In a well-run spectrum, you expect to see some, but not all, possible adducts. Knowing how to spot these adducts based on their relative mass differences can help you make sense of your data. To help you out, we’ve assembled some of the most common adducts and their corresponding masses in the tables below. Common Adducts in Positive Ion Mode
What mass is lost from M+ to give these peaks? What ions could give these peaks? If available, use IR data to identify functionality, and consider known fragmentation patterns of these groups.
You might wish to refer to the table of bond dissociation energies when attempting problems involving the interpretation of mass spectra. This page looks at how fragmentation patterns are formed when organic molecules are fed into a mass spectrometer, and how you can get information from the mass spectrum.
Explore the diverse ion types and fragmentation processes in mass spectrometry, revealing valuable insights into molecular composition and structure. Learn about molecular ions, isotopic ions, fragment ions, rearrangement ions, and more.
22 cze 2012 · The following table provides a guide to the identification and interpretation of commonly observed mass spectral fragmentation patterns for common organic funct
What fragment ions are characteristics for glucuronide conjugates? What happens with aliphatic sulfates in MS/MS? Aliphatic and aromatic sulfate conjugates behave differently in MS/MS aliphatic typically show m/z 97 (HSO4-) and m/z 80 (SO3-.) Source: Weidolf et al. Biomed. and Environ.
