Description

Gas chromatograph shell assembly

Technical Field

The utility model relates to a detection device technical field specifically is a gas chromatograph casing subassembly.

Background

Gas chromatography is a separation technique. In practice, the sample to be analyzed is often a multi-component mixture in a complex matrix, and for samples containing unknown components, it must first be separated before further analysis of the component concerned can be performed. The separation of the mixture is based on the difference of the physicochemical properties of the components, and the gas chromatography mainly utilizes the difference of the boiling point, the polarity and the adsorption property of the substances to realize the separation of the mixture. The sample to be analyzed is carried by an inert gas (i.e., a carrier gas, typically N2, He, etc.) into a chromatographic column containing a liquid or solid stationary phase after vaporization in a vaporization chamber, each of which tends to form a partition or adsorption equilibrium between the mobile and stationary phases due to differences in boiling point, polarity, or adsorption properties of the components in the sample. However, since the carrier gas is flowing, such equilibrium is difficult to establish in practice, and it is the flow of the carrier gas that causes the sample components to be repeatedly distributed or adsorbed/desorbed in motion many times, so that the components having a large distribution concentration in the carrier gas flow out of the column first, and the components having a large distribution concentration in the stationary phase flow out. When the components flow out of the chromatographic column, the components immediately enter the detector, and the detector can convert the existence of the sample components into an electric signal to be displayed through the display screen, but the existing gas chromatograph still has certain defects, has certain harmfulness to the environment or human body and is not beneficial to long-term use.
