Abstract (en)
[origin: DE4419860A1] A process and filter for producing NO2-free nitrogen monoxide are based on putting a NO2-containing gas or liquid in contact with a material that contains a sulphurous polymer, for example polyarylene thioether, in particular polyphenylene sulphide. The process or filter are suitable for generating NO2-free nitrogen monoxide-nitrogen-air mixtures for medical applications.
