The leakage of propellants from missiles in shipboard spaces is a potential hazard to ships personnel. It is essential to develop systems that can detect and automatically alarm to hazardous concentrations of such materials. The detection of the fuel UDMH unsymmetrical dimethylhydrazine was studied by gas chromatography and FMIR frustrated multiple internal reflectance spectroscopy. By means of a gas chromatograph equipped with a flame ionization detector, 3ppm of UDMH in air could easily be detected in 20 seconds. The data indicated that the desired sensitivity of 0.5 ppm was attainable. By means of FMIR, 10 micrograms UDMH in benzene could be detected, but whether such small quantities can also be detected in air has not yet been determined. Author
