　　An analysis was conducted on the production methods of thermal conductivity detectors (TCDs) both domestically and internationally in recent years, as well as the selection of thermal sensitive components, methods for reducing cell volume, and other methods for improving sensitivity.

　　Thermal conductivity detector (TCD) is a core component in gas chromatography systems. Compared with traditional thermal conductivity detectors, micro thermal conductivity detectors（ μ TCD has the advantages of light weight, small size, and high sensitivity. However, μ The various processes, high preparation accuracy, and high cost of TCD make the development of micro thermal conductivity detectors difficult.
