Abstract
Intellitec, a division of Technical Products Group, Inc., is developing and testing a ruggedized commercial spectrometer for stable platform applications. This spectrometer design incorporates the key components utilized in the M21 remote sensing chemical agent alarm (RSCAAL). The spectrometer, which has a resolution of 4 wavenumbers (cm-1), can be used to remotely sense fugitive vapors with spectral features in the 8 - 12 micrometer region. Intellitec has initiated a parallel effort to complete the development of personal computer (PC) based vapor identification software. The spectrometer's detection capability was tested by placing small amounts of anhydrous hydrazine vapor in a cell positioned in front of a black body reference. The data collected from the spectrometer clearly showed characteristic spectral features of hydrazine vapor. A developmental set of hydrazine coefficients was generated for use with the vapor identification software utilized in the M21. The coefficients were programmed into the M21. The effectiveness of the coefficients in the M21 was then tested by attempting to detect hydrazine vapor contained in a cell positioned in front of a black body. The developmental coefficient set successfully detected the hydrazine vapor. Further testing is required to improve detection sensitivity and confirm the spectrometer's ability to detect these vapors in an open path environment.
