  • Gas chromatographic

A gas chromatographic method for the chromatographic separation of volatile and non-dissolvable to check that they can be. In gas chromatography, gas phase inert phase (for example, helium , nitrogen , argon and carbon dioxide ) and the mobile phase is a carrier gas, as they say. Stationary phase is a solid adsorbent or a thin layer of a non-volatile liquid to the inner wall of the column or as a coating on the surface of glass or metal spheres has been given. If the stationary phase is a solid adsorbent and if so-called gas chromatography stationary phase is a nonvolatile liquid to gas liquid chromatography say. But both are known as gas chromatography. In gas chromatography, separating a mixture of proportional distribution of the components of the mobile phase mixture of gas and solid or liquid stationary phase. The mixture of carrier gas through the column moves the equilibrium between the two phases (gas-liquid) are the components of the mixture distribution. The mobile phase components of the sample to the column moves out of the relationship Ssttr molecular absorption column, the sooner the better part of the absorption column, the column is longer than go. Therefore, the components separated are mixed. Gas chromatography to separate and identify the components of a mixture and their quantitative analysis applications.
