Gas Chromatography
Gas Chromatography or GC, is a common type of chromatography using in analytical chemistry for seperating and anaylyzing compounds that can be put into the gas phase without decomposition. This method is also useful for determining the purity of certain samples and/or seperating said sample into multiple compounds for analysis.
Decomposition
Is a method of seperation of a chemical solution into two more more phases. Samples are usually exposed to conditions such as; heat, radiation or the acidity of a solvent.
Chromatography
Is a method of seperating a mixture. The mixture is disolved into fluid known as the Mobile Phase which is then carried through the a material known as the Stationary Phase. The seperation is then based on the partitioning of the two phases.
Key Words
Carrier
This can loosely be defined as the Mobile Phase or rather the substance that is carrying the analyte through the stationary phase. In GC the carrier is an inert or unreactive gass like Helium or Nitrogen.
History
Chromatography itself was developed in 1906 by a Russian Scientist by the name of Mikhali Tsvet while he conducted his research on plant Pigmentation. Through use of liquid-adorpstion column chromatography he was able to isolate chlorophylls and carotenoids.
In 1952 the Nobel Prize in chemistry was awarded to Archer John Porter Martin (left) and Richard Laurence Millington Synge (right) for their development of Partition Chromatography which lead to the further developement of Gas Chromatography.
