These include Column chromatography, High performance liquid chromatography (HPLC), Gas chromatography, Size exclusion chromatography, Ion exchange chromatography etc. Why Choose this Training Course? In the past 50 years, Gas Chromatography has become an important analytical tool in virtually every phase of the petroleum industry, from exploration of crude oil and refining of finished products to research on new petrochemicals. Although GC can be used for preparative purposes, it is most commonly used for analytical work. Scribd is the world's largest social reading and publishing site. Mixtures can also be separated by gas-phase chromatography, which takes advantage of the relative affinity of the different components in a mixture for the stationary support when the mixture is heated until there is an equilibrium between its gas and liquid phases. Recent Journal of Chromatography A Articles Recently published articles from Journal of Chromatography A. They are the latest and best method, but they cannot replace totally the packed columns. Polite, Practical Gas Chromatography There is no flow controller on the column… flowrate through column is controlled by the head pressure of the column based on its characteristics (diameter and length) Keeps air from a. The injection precision of a headspace injector can consistently give < 10. And the stationary phase is an involatile liquid held on particles of a solid support. In principle liquid chromatography (LC) and high performance liquid chromatography (HPLC) work the same way except the speed, efficiency, sensitivity and ease of operation of HPLC is vastly superior. Partition chromatography:.
