INDICATOR COMPOSITION FOR EXPRESS-DETECTION OF ASYMMETRICAL DIMETHYLHYDRAZINE AND AMMONIA Russian patent published in 2015 - IPC G01N31/22 

FIELD: chemistry.

SUBSTANCE: invention relates to indicator compositions for the express-detection of the presence of asymmetric dimethylhydrazine (ADMH) and ammonia by indication on surfaces, in particular for the control of the integrity of reservoirs, pipe lines and aggregates of chemical industries, objects of storage and destruction of rocket fuel components, as well as for sanitary-chemical control. An indicator composition represents a 10-20 wt % water solution of cobalt(II) acetate in distilled water, placed into an aerosol device, made in the form of a hermetic case with a pump-sprayer.

EFFECT: increase of sensitivity, clearness of the indication effect and the term of preservation of the work capacity of the aerosol device for the detection of asymmetrical dimethylhydrazine and ammonia on horizontal, inclined and vertical surfaces.
