| abstract | (57) [Summary] [Problem] To obtain nitrogen gas from liquid air, although there was no simple method for measuring the purity of nitrogen gas. Apart from the method, in the method of obtaining nitrogen gas by deoxygenating means that increased the purity of nitrogen gas by consuming oxygen in the air, there was also concern that the purity of nitrogen gas was ensured. Means An oxygen detecting means 60 for measuring the concentration of oxygen is provided downstream of the deoxidizing means 50 which consumes oxygen by oxidizing iron powder to increase the purity of nitrogen gas. |
