WebDescription of Gas Chromatography Giovanni Tosi* Department of Pharmaceutical Technology, University of Modena and Reggio Emilia, Emilia-Romagna, Italy EDITORIAL NOTE Gas chromatography (GC) is a typical sort of chromatography utilized in scientific science for isolating and dissecting intensifies that can be disintegrated without decay. … Gas chromatography (GC) is a common type of chromatography used in analytical chemistry for separating and analyzing compounds that can be vaporized without decomposition. Typical uses of GC include testing the purity of a particular substance, or separating the different components of a mixture. In … See more A gas chromatograph is made of a narrow tube, known as the column, through which the vaporized sample passes, carried along by a continuous flow of inert or nonreactive gas. Components of the sample pass … See more The method is the collection of conditions in which the GC operates for a given analysis. Method development is the process of determining what conditions are adequate … See more In general, substances that vaporize below 300 °C (and therefore are stable up to that temperature) can be measured quantitatively.
