The invention concerns a method of storing a NO/N2 mixture in a packaging container (6), in particular a gas bottle, having an internal volume less than or equal to 12 litres, characterised in that a NO/N2 gaseous mixture containing between 400 ppm and 1000 ppm by volume of NO and nitrogen for the remainder is held at a pressure of at least 250 bar in the internal volume of said container. Preferably, the NO/N2 gaseous mixture is held at a pressure of 280 to 450 bar, and preferably between 300 and 420 bar. |
