The working principle of gas chromatograph

Using the different distribution coefficients of the components in the sample between the gas phase and the liquid phase of the stationary liquid, when the vaporized sample is carried by the carrier gas into the chromatographic column, the components will be repeatedly distributed between the two phases, and the components will run at different speeds in the column due to the difference in adsorption or solvency of the stationary phase, after a certain column length, they will be separated from each other and leave the column in order to enter the detector, and the resulting gas chromatograph will be used as a gas chromatograph. After a certain column length, they will be separated from each other, in order to leave the column into the detector, the resulting ion flow signal is amplified, and the chromatographic peaks of each component are depicted on the recorder.
