Abstract: Disclosed are a gas purification device, and an apparatus and a method for measuring isotopes of noble gases. The gas purification device includes a housing and a purification mechanism. The housing is provided with a reaction chamber. The reaction chamber is in a vacuum state and is configured to hold a gas sample. The purification mechanism is arranged on the housing and is provided with a cavity. The cavity in the purification mechanism is communicated with the reaction chamber. The purification mechanism is configured to purify the gas sample in the reaction chamber to obtain a purified gas.
