Belonging to the technical field of liquid-gas separation, the invention provides a rare gas separation device and a control method thereof. The separation device comprises a separation chamber, a heater, a purification apparatus, a liquid collection chamber, a liquid storage chamber and the like. The separation device provided by the invention can separate rare gas in liquid with high precision in a short time. In an early sampling process, a design scheme separating sampling from storage is adopted, and can effectively avoid the mixing of air, in the separation process, a novel cold trap structure can quickly filter out water vapor in gas, the disposed purification apparatus can eliminate active gas in mixed gas, and the purified rare gas can be directly measured through a flow meter anda mass spectrometer. The device is particularly suitable for separating and researching rare gas dissolved in underground water. 本发明提供了一种稀有气体分离装置及其控制方法，属于液气分离技术领域，该分离装置包括分离室、加热器、纯化装置、采液室和存液室等，本发明提出的分离装置能够在短时间内、高精度的分离出液体中的稀有气
