This video, part of the knowbeetutoring collection available from Wordpress.com offers a basic but effective introduction to ion production of organic molecules in an electron ionization spectrometer. The basis for fragmentation is explained for the propane molecule using very clear graphics. It is an excellent first exposure to the technique, and supplies a very solid…
A set of slides that explain in detail the important aspects of interpreting EI mass spectra as obtained in GC-MS. The site explains how to use common losses (e.g. water), use of isotopic peaks, mass defects, the nitrogen rule and identifying the presence of rings and unsaturated bonds..

This publication highlights a collaboration between academia and industry to deliver a course of mass spectrometry. Highlighted in the text are instructor qualifications, instructor roles, student assignments, and student perceptions.The website is available here .
A basic tutorial on the principles of Time-of-flight mass spectrometer design, presenting the concepts of ionization, acceleration from an ion source, energy dispersion of the ions due to space dispersion in the source, and the use of an ion mirror to focus this dispersion. The two-field source, the ion mirror, and the MCP ion detector is…
This site offers a concise, clearly-written introduction to general techniques of mass spectrometry. It includes descriptions and illustrations of various types of mass spectrometers and covers the major ionization techniques.The website is available here .
Easy to use calculator for the isotopic distribution of a given chemical formula. Distributions can be plotted either for a formula, or user input of mass/intensity data. Either high or low mass resolution calculations can be performed. Simple program doing one task well.The website is available here .
This video, distributed on YouTube by the Royal Society of Chemistry is on the basic principles of mass spectrometry, using a magnetic sector instrument to demonstrate how specific m/z ratios can be selected. The theory and operation of MS, including the chemistry of ionization and fragmentation is described at an introductory level. There's also an excellent…
This video, developed at Lawrence Livermore National Laboratory, describes the instrumentation for accelerator mass spectrometry and its applications. The video describes the instrumentation and its application for carbon dating and measurements of drug distribution.The website is available here .
This website provides resources that can aid in the assigning NMR proton shifts, IR peaks and mass loss in mass spectrometry. The original site is in German, but most (but not all) the content is translated on the English version of the site. From the left hand menu under Spektroskopei-Tools choose Wizards. From here you can…
