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.

Apr 11, 2025 · Learn how to read and interpret mass spectra, recognize fragmentation patterns, and apply the data in analytical chemistry.

A typical mass spectrum (shown below) plots the different mass-to-charge ratios (m/z) against their abundances (occurrence of a certain ion divided by the occurrence of the most plentiful …

A mass spectrum will usually be presented as a vertical bar graph, in which each bar represents an ion having a specific mass-to-charge ratio (m/z) and the length of the bar indicates the …

May 7, 2015 · Mass spectrometry allows us to measure the masses of atoms and molecules, and also obtain information about their chemical structure. Before we talk about interpreting …

This website allows plotting and labelling of a single mass spectrum as well as creating an overlaid plot or mirror plot of two mass spectra. Additionally, parameters of selected peaks …

Mar 14, 2025 · The output of a mass spectrometer, the mass spectrum, provides a wealth of information about the composition of a sample. This article provides a detailed guide to …

In summary, a deep understanding of mass spectrometry graphs, especially the X-axis, Y-axis, and isotopic patterns, is crucial for accurate data interpretation and improved analysis in …

Follow this order when looking for information provided by isotopes: (A simplified table of isotopes is provided in the introduction, more detailed tables can be found in chemistry texts.) Postulate …

What Is Mass Spectrometry and What Is it Used For? Mass spectrometry (MS) is an analytical tool used to determine the masses of different compounds in a sample.
