The separation of the mixture is based on the difference in the physicochemical properties of the components. GC mainly uses the difference in boiling point, polarity and adsorption properties of the material to achieve separation of the mixture Gas chromatography vials. After the sample to be analyzed is vaporized in the vaporization chamber, it is carried into the column by an inert gas (ie, carrier gas, generally N2, He, etc.). The column contains a liquid or solid stationary phase due to the boiling point, polarity or adsorption of each component in the sample. Depending on the performance, each component tends to form a distribution or adsorption equilibrium between the mobile phase and the stationary phase. However, since the carrier gas is flowing, this balance is actually difficult to establish, and it is precisely because of the flow of the carrier gas that the sample components are repeatedly distributed or adsorbed/desorbed during the movement, and the result is in the carrier gas.

The component with a large concentration in the middle flows out of the column first, and the component with a large concentration is distributed in the stationary phase and then flows out. When the component flows out of the column, it immediately enters the detector. The detector can convert the presence or absence of the sample component into an electrical signal, and the size of the electrical signal is proportional to the amount or concentration of the component being measured. When zoomed in and recorded, it contains all of the original information for the chromatogram Gas chromatography vials. When no components are flowing out, the chromatogram is recorded as the background signal of the detector, the baseline of the chromatogram.
