    • The present invention relates to a method and a device for the measurement of NO contents in liquids using an inert carder gas. The device consists of a micro reaction part FIG. 1 which is divided into an inert gas inlet nozzle 1, the microreaction vessel 2 with frit 3, at least one inlet nozzle for the injection of the liquid to be analyzed 4, as well as a cooled outlet nozzle for the inert gas loaded with NO 5, and a detector 6, with which the NO content of the inset liquid is measured and evaluated, and where the NO.sub.2 - ions present in the solution are reduced back to NO using a reaction mixture consisting out of 1,1'-dimethylferrocene in acetonitrile in an acidic medium, preferably perchloric acid.
