• Ion Cyclotron Resonance (ICR) Program
  The MagLab's ICR program develops and exploits the unique capabilities of FT-ICR mass spectrometry. The program leads the world in instrument and technique development as well as pursuing novel applications of FT-ICR mass spectrometry.
• Alan Marshall: A Scientist and a Gentleman
  Profile of ICR Program Director Alan Marshall, co-inventor of Fourier Transform Ion Cyclotron Resonance.
• Mass Spectrometry: How to Weigh an Atom
  This article covers how mass spectrometry is used to examine comet dust.
• Right and Left Hand Rules
  Interactive Java Tutorial: You’ll find two of the most useful tools for understanding electromagnetism right at the end of your arms.
• Single Sector Mass Spectrometer
  Interactive Java Tutorial: The single sector mass spectrometer is made with a single magnetic analyzer.
• Dual Sector Mass Spectrometer
  Interactive Java Tutorial: The dual sector mass spectrometer has two analyzers – one magnetic, one electrostatic.
• Mass Spectra
  Interactive Java Tutorial: The mass spectrum of a material, deduced using a machine called a mass spectrometer, reveals how many isotopes of a given element are to be found in the material. See here what these spectra look like and how they are useful.
• Tools of the Trade – Atmospheric Pressure Photoionization (APPI)
  All mass spectrometers require the molecules to be in the gas phase and charged. In this technique, UV light photons are used to ionize sample molecules.
• Tools of the Trade – Electrospray ionization (ESI)
  This popular ionization technique works well with heavier compounds and is therefore often used in the analysis of proteins and petroleum.
• Tools of the Trade – Matrix-Assisted Laser Desorption Ionization (MALDI)
  This method of ionization, widely used since its introduction in the late 1980s, has been of great help to scientists studying polymers, proteins and other heavy molecules.
• Reading Chemical "Fine Print": The Key to Unlocking Nature's Isotopic Zoo
  This link directs you to an online video of a presentation given by ICR Program Director Alan Marshall in November 2006.
