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.
