Gas Chromatograph Mass Spectrometer (GC/MS)

What is it?

cg mass spectrometer: bowdoin chemistry GC/MS is a technique that uses the combination of a gas chromatograph (GC) to separate compounds in  a mixture to a mass spectrometer (MS) for identification and quantification.  The MS produces ions with a +1 charge in a vacuum that can be “weighed” to determine the mass of the original molecule.  Fragment ions can be used to determine molecular structure.

The GC/MS instruments at Bowdoin are used by students taking Molecular Structure Determination, Quantitative Analysis, and Instrumental Analysis.  The instrument is heavily used by students for their research.

Applications:

GC/MS is used for structure determinations and is parcticularly useful when dealing with mixtures of compounds that may be present at low concentrations. This is also an important technique for quantitative measurements.
