(GC) is an analytical separation technique used to analyze volatile substances that do not degrade or decompose in the gas phase. The sample is dissolved in a solvent and vaporized in the instrument. The mobile phase, a chemically inert gas, such as helium or nitrogen, serves to carry the vaporized analyte through a stationary phase which is coated inside the capillary column that is also maintained at an elevated temperature. The analyte mixture separates on the stationary phase leading to chromatographic separation of the molecules. In principle, gas chromatography is similar to other chromatography techniques such as thin layer chromatography and high performance liquid chromatography. This can be coupled with a mass spectrometer or other detection methods.
