Background

The gas chromatograph is a chromatographic analysis device using gas as a mobile phase. The principle is mainly to realize the separation of the mixture by utilizing the differences of the boiling point, the polarity and the adsorption property of the substances. After being gasified in the gasification chamber, the sample to be analyzed is carried into the chromatographic column by inert gas (i.e. carrier gas, also called mobile phase), the column contains liquid or solid stationary phase, and each component in the sample tends to form distribution or adsorption equilibrium between the mobile phase and the stationary phase. With the flowing of the carrier gas, the sample components are repeatedly distributed or adsorbed/desorbed in motion for many times, and the components with high distribution concentration in the carrier gas flow out of the chromatographic column firstly, and the components with high distribution concentration in the stationary phase flow out after being distributed. The components exit the column and enter a detector for determination. The method has the advantages of rapidness, effectiveness, high sensitivity, high working stability and the like, and plays an important role in the research of soil organic matters.
