Description

Technical Field

[0001] This utility model relates to a gas chromatograph gas supply pipeline that is easy to connect, and belongs to the field of gas chromatograph technology. Background Technology

[0002] A gas chromatograph (GC) is an analytical instrument based on gas chromatography technology. It is primarily used to separate and analyze volatile components in mixtures and is widely applied in fields such as chemistry, environmental science, and medicine. GC utilizes chromatographic separation and detection techniques to perform qualitative and quantitative analysis of complex multi-component mixtures. It is typically used to analyze thermally stable organic compounds in soil with boiling points not exceeding 500°C, such as volatile organic compounds, organochlorines, organophosphorus compounds, polycyclic aromatic hydrocarbons, and phthalates.

[0003] Chinese Patent Publication No. (CN 221004727 U) discloses an air supply device that facilitates connection to an air pipe, relating to the field of air supply device technology. The device includes a main body, with a main shell movably mounted on the top of the main body. A ventilation slot is opened and penetrates the surface of the main shell, and an air leakage module is fixedly installed on the inner wall of the main body. This invention solves the problem of existing air supply devices being inconvenient to connect to air pipes during use, requiring bolts (12) to fix them during connection, resulting in inconvenient air pipe connection. By combining the above structures, the air supply device can be directly connected by inserting the air pipe into the connection mechanism during use. By providing a quick-connect and disassembly connector for the connecting air pipe, it facilitates quick replacement of the air supply pipe according to different connected devices, and enables quick connection between the air supply pipe and the air supply equipment and the air-requiring equipment. Existing gas chromatographs require the delivery of detection gas into the instrument for analysis. However, the current connection method uses a knob to fix the delivery tube, which reduces the seal of the knob over time, leading to gas leakage and affecting the detection results.

[0004] Therefore, a gas chromatograph gas supply pipeline that is easy to connect is proposed. Utility Model Content
