Infrared Spectroscopy and Mass Spectrometry
crab.rutgers.eduMass Spectrometry (MS) MS provides information concerning the molecular weight of a molecule (and often other structural information). Very small sample sizes are required (2mg, "if you can see it, you can MS it", but a destructive technique), and high resolution mass spectrometry (HRMS) can determine molecular weight to 3-4 decimal places.

The capability of a mass spectrometer to differentiate between masses is usually stated in terms of its resolution which is defined by ~ L ∆ Equation 1: ~ L ∆ Equation 1 In the equation, ∆ is the mass difference between two adjacent peaks that are just resolved, and m is the nominal mass of the first peak.
Time-of-Flight Mass Spectrometry
www.agilent.comTime-of-flight mass spectrometry (TOF MS) was developed in the late 1940’s, but until the 1990’s its popularity was limited. Recent improvements in TOF technology, including orthogonal acceleration, ion mirrors (reflectron), and high-speed electron-ics, have significantly improved TOF resolution. This improved resolution, combined
