The process of chromatographic separation: gas chromatography. P3031740

You can get the concept of:
Chromatography, Chromatogram, heat sensor, Nernst distribution law.

Principle:
Chromatographic methods allow us to separate mixtures of substances are in stationary and mobile phases. In gas chromatography, mobile phase - gas, which transports the material through the separation column with a constant flow. Establishing a balance between the constant phase and various Substance leads to different standards of individual travel components. At the end of the column cell detects the heat of various substances on the basis of their differing thermal conductivity. A mixture of butane gas and a two-component mixture consisting of ethanol and ethyl acetate, separated and identified by chromatographic.
