Gas Chromatography-Mass Spectroscopy

Gas Chromatography-Mass Spectroscopy Introduction Gas Chromatography-Mass Spectroscopy (GC-MS) is one of the so-called hyphenated analytical techniques. As the name implies, it is actually two techniques that are combined to form a single method of analyzing mixtures of chemicals. Gas chromatography separates the components of a mixture and mass Spectroscopy characterizes each of the components individually. By combining the two techniques, an analytical chemist can both qualitatively and quantitatively evaluate a solution containing a number of chemicals. Gas chromatography In general, chromatography is used to separate mixtures of chemicals into individual components. Once isolated, the components can be evaluated individually. In all chromatography , separation occurs when the sample mixture is introduced (injected) into a mobile phase.

Gas Chromatography-Mass Spectroscopy

Mass Spectroscopy As the individual compounds elute from the GC column, they enter the electron ionization (mass spec) detector. There, they are bombarded with a stream of electrons causing them to break apart into fragments. These fragments can be large or small pieces of the original molecules.

Infrared Spectroscopy and Mass Spectrometry

Mass 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.

Time-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
