Gas chromatography uses the differences in solubility and adsorption between the mobile phase (carrier gas, such as inert gases such as nitrogen and helium) and the stationary phase (liquid or solid coating in the chromatographic column) to separate the components in a mixture. During use, the chromatograph needs to be assisted in heat dissipation by air cooling, and the ventilation pipe must be shielded and protected by a filter.
