| 摘要 |
<p>The invention concerns a conditioned NO/CO2 mixture containing at least nitric oxide (NO) and carbon dioxide (CO2), characterised in that it is in supercritical state. Preferably, said NO/CO2 mixture pressure is higher than about 73.105 Pa at 304.21 K. The invention also concerns a pressurised container, such as a gas cylinder, containing such a supercritical NO/CO¿2? mixture and a method for expanding such NO/CO2 mixture to ensure a constant concentration in NO while the gas cylinder is being emptied.</p> |
