Gas chromatographyGas chromatography is an instrument that use chromatography column for separating components of chemical mixtures. Mixtures are injected into the injector and after vaporization, the component convey into the separating column using a carrier gas. Separated components are then conveyed toward the column outlet in order of time.In this method, components are separated owing to their chemical nature (molecular weight, polarity and boiling temperature of the injected sample), specifications of the static gas chromatography column (polar, semi-polar and non- polar) and also the nature of the carrying gas.The detector (usually FID) converts chemical signal to electrical signal and also to digital signal that is then converted into a graph using the provided computer software. The peak Retention Time in graph determines the quality of the component and the area of the peak determines the quantity of the component.Application:Gas chromatograph that is very fast and easy chromatography method is widely used in below field: Oil and petrochemical industry.
