Abstract

The invention discloses a quantitative loop for gas transfer and a gas transfer method, and belongs to the field of analytical measurement. By means of the quantitative ring for gas transfer, an experimenter can temporarily store gas in an inflation device in the quantitative ring and transfer the gas into a gas storage device through the quantitative ring, gas extraction is conducted on the quantitative ring before gas transfer, meanwhile, all the assemblies are in airtight connection, and the gas transfer efficiency is improved. The purity of the gas in the gas transfer process can be ensured. The mass change of the quantitative ring in the gas transfer process is measured through the weighing apparatus, the mass of the transferred gas can be obtained, and therefore the accurate gas transfer amount is provided for experimenters.

Description

technical field [0001] The application relates to the field of analysis and measurement, in particular to a quantitative loop for gas transfer and a gas transfer method. Background technique [0002] In experiments related to gas, the gas transfer process is usually involved, such as transferring the gas to a reaction vessel for experimentation, or transferring the gas prepared in the experiment to an analytical test instrument for testing, etc. [0003] In related technologies, a syringe is often used for intermittent gas transfer, that is, the gas is sucked into the cavity of the syringe, and then the gas in the cavity of the syringe is transferred to the required place. However, due to the structural limitation of the syringe, the experimenters could not know the amount of transferred gas during the gas transfer process, which affected the accuracy of subsequent experiments. Contents of the invention [0004] The embodiments of the present application provide a quantit...
