Gas chromatography (GC)

Gas-Chromatography is an analytical technique which allows to separate and to quantify the components of an organic products mixture. The identification of such components can be obtained by comparison with authentic samples.
This technique is usually applied to show the results of a reaction under investigation by separating and quantifying reactants from products, in order to evaluate the effects of the experimental conditions on activity and selectivity. The mixture has to be solved in a solvent and injected in the gas-chromatograph. All the components are eluted through the capillary column with different velocity and the they pass through the detector giving as final result a graph reporting Intensity Vs. time. The choice of the column and of all the analysis parameters (i.e.: programmed Temperature Vs. time) allows the separation and quantification of compounds with very similar chemical characteristics.
