Ashay Mehta Analytical Chemistry Professor Pin Gu 12/8/09 Chromatography dates back to 1903 where it was first seen in the works of a Russian scientist named Mikhail Semenovich Tswett. After that, a German graduate student, Fritz Prior, developed solid state-gas chromatography in 1947. A Nobel Prize winner, Archer John Porter Martin, developed liquid-liquid chromatography in 1941 and paper chromatography in 1944. He actually won the Nobel Prize for these very developments and, thus, laid the foundation for the development of gas chromatography and which later produced liquid-gas chromatography in 1950. Gas chromatography, (GC), is a widespread type of chromatography used in analytic chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of gas chromatography include testing the purity of a particular substance, or separating the different components of a mixture. We can also find out the relative amounts of such compositions. In some cases, GC may help in identifying a compound. In preparative
