Identifying Unknown Gas Chromatography

No view

Gas chromatography GC is a method of separating "volatile" compounds. those with a high-vapor compound is a function of the intermolecular forces between molecules, GC takes advantage of differences in at least one of the The purpose of the experiment is to determine the composition of the unknown solutions..Is it possible to do GC for the sample and then comparison of results to the online databases for compound identification? How do Iyze the results from gas chromatography GC-TCD ? How can I calculate the concentration from a gc/ms chromatogram which is having retention time .Background and Objectives. There are several different types of chromatography including paper, thin layer TLC , liquid, high-pressure liquid. HPLC , and gas GC . Chromatography is applied in many fields. Biochemists use liquid chromatography to separate proteins. Organic chemists use GC, TLC, and HPLC to identify .THE identification of unknown compounds separated by gas chromatography is often effected by comparison of their retention values with those of known compounds together with infra-red spectro-p.ometry or mspectrometry. For this purpose graphs are prepared of log r against boiling point or log r on one stationary .
