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.
Claims17
A gas purification device, comprising:
- a housing;
- and
- a purification mechanism;
- wherein the housing is provided with a reaction chamber;
- the reaction chamber is in a vacuum state and is configured to accommodate a gas sample;
- the purification mechanism is arranged on the housing and is provided with a cavity;
- the cavity is communicated with the reaction chamber;
- and the purification mechanism is configured to purify the gas sample in the reaction chamber to obtain a purified gas.
A method for measuring noble gas isotopes, comprising:
- feeding a gas sample into a reaction chamber of the casing;
- turning on a water vapor removal assembly to remove water vapor in the gas sample;
- turning off the water vapor removal assembly, and turning on a reactive gas removal assembly to remove reactive gases in the gas sample treated by the water vapor removal assembly;
- turning off the reactive gas removal assembly, and turning on a hydrogen gas removal assembly to remove hydrogen in the gas sample treated by the reactive gas removal assembly;
- turning off the hydrogen gas removal assembly, and separating noble gases in the gas sample treated by the hydrogen gas removal assembly;
- and
- turning on a noble gas isotope mass spectrometer to measure isotopes of individual noble gases.
