In the analysis of high-efficiency gas-liquid partition chromatograph, clear crimp vials the carrier gas is emotional, the concentration of the components in the carrier gas is very low, and the interaction between the components and molecules is small and can be ignored. In the analysis of high-efficiency liquid-liquid partition chromatograph, the concentration of the components in the mobile phase is low, and the force between the constituent molecules is negligible. The main force in efficient partition chromatography is the interaction between the component molecules and the immobilized liquid molecules, which reflects the thermodynamic properties of the components in the fixative.

The component with high force has a large partition coefficient due to its high solubility. The selectivity of the high-efficiency partition chromatograph analysis is mainly determined by the difference in molecular structure and interaction clear crimp vials force between the components and the fixative.
This is the end of the introduction of What is the selectivity of the efficient partition chromatographic analysis? I hope it can help you.
