  • Patent number: 11105470
    Abstract: The present invention relates to a method for determining loss of gas in a gas container. According to an embodiment of the present invention, the method for determining the loss of gas in the gas container is characterized by including the steps of (a) filling a first container (10) with a component gas and a balance gas, (b) measuring a gas pressure inside the first gas container (11), (c) allowing the first gas container and a second gas container having an evacuated inside to communicate and performing a first-stage gas pressure split, and (d) measuring a gas pressure inside the second gas container, wherein an amount of the component gas adsorbed inside the gas container is calculated through a difference between a measured value of step (b) and a measured value of step (d) and is determined as an amount of gas loss.
