Study Notes
Mass Spectrometry (MS) Analysis
- MS analysis provides information about molecular weight of a compound
- It determines the number of specific elements in a compound based on isotope peaks
- High-resolution MS analysis allows for the determination of molecular formula
- MS analysis yields reproducible fragment patterns, which are useful for: • Identifying functional groups • Determining arrangement of components • Confirming compound identity
