Abstract:

The present work relates to the development of technology suitable for the field measurement of hypergolic propellants including Hydrazine H, Monomethyl-hydrazine MMH, and unsymmetrical-dimethylhydrazine UDMH at the parts-per-billion PPB level in air or a diluent gas. The Space Shuttle Transportation System and F-16 Aircraft programs, as well as other military and commercial users, will require the handling of large quantities of hydrazine H, MMH, and UDMH. These compounds are highly toxic and recommended maximum exposure limits are 0.1 PPM for H, 0.2 PPM for MMH, and 0.5 PPM for UDMH. There is a need, therefore, for a measurement technique which can be used to aid compliance with health and safety regulations. This instrumentation should be capable of 1 certifying that the work area is free from hydrazines contamination, 2 accurately measuring the hydrazines level to document exposures, 3 checking for leaks around valves, tanks and transfer lines, and 4 warning when hazardous situations occur. In this study, a real-time instrument was developed for the convenient measurement of hydrazine at PPB levels in the air. It was deployed initially at Kennedy Space Center for monitoring during operations. The important instrument features that allow for portable field operation as well as the important operating characteristics are discussed.
