Peaks in mass spectrum
WebThe mass spectrum is a plot of number of molecule-like particles detected vs net mass of that particle. So a peak shows that the vapor that supplies particles has a relatively large number of particles of exactly that mass. Each mass implies a … WebNov 8, 2024 · Mass spectrometry in general is useful for structure elucidation (when combined with chromatography separation techniques), peptide sequencing (when combined with ion traps), and quantification (when combined with a triple-quadrupole mass analyzer) for example, and is mainly limited by the ability of the ions generated to remain …

WebJun 7, 2024 · Prominent peaks in a mass spectrum are generally those resulting from primary fragmentations. Secondary fragmentations may be used as aids for spectrum analysis. Fragment ions of higher mass close to that of the molecular ion are easy to identify because they correspond to formation of a small neutral entity such as CH 3, CH 2 =CH 2, …
