This invention belongs to the field of gas enrichment technology and provides a gas enrichment device and method based on a semiconductor cooling chip. The device includes a heat-insulating shell, inside which a cooling chip, a first heat sink, and a second heat sink are installed. A first adsorption tube and a second adsorption tube are respectively installed on both sides of the cooling chip. A sample source, a carrier gas source, and an analysis system are also provided. During operation, the cooling chip enriches the gas on its cooled side, while the heated side performs desorption. Then, the semiconductor electrodes are reversed, and the cooling and heating areas are interchanged. This design fully utilizes the effects of both sides of the cooling chip, avoiding energy waste. Furthermore, the first and second adsorption tubes operate independently without interference, ensuring a continuous and uninterrupted gas enrichment and desorption process. This significantly improves detection efficiency and reduces the overall process time.
