FIELD: chemistry.
SUBSTANCE: indicator element leak detection hydrazine missile combustibles consists of paper-the basics for express tests, impregnated indicator, which contains potassium tetrahydro-12-molybdosilicate in the range 10-28 wt % and iminodiacetic acid in the range 1-5 wt %, where impregnated paper is duplicated with waterproofing substrate.
EFFECT: invention allows to increase the sensitivity, accuracy and rapidity of microquantity of leakage of liquid and gaseous asymmetical dymethylhydrazine.
