The invention relates to a method for storing a NO / N 2 mixture in a conditioning container (6), in particular a gas cylinder, having an internal volume of less than or equal to 12 liters, characterized in that retains a gaseous NO / N 2 mixture containing from 400 ppm to 1000 ppm by volume of NO and nitrogen for the rest, at a pressure of at least 250 bar in the internal volume of said container. Preferably, the gaseous mixture NO / N 2 is stored at a pressure of 280 to 450 bar, preferably between 300 and 420 bar. |
