Because of potential environmental effects from the large quantities of HCl released into the atmosphere from Space Shuttle launches, it is important to monitor the transport of HCl in both vapor and aerosol form into the surrounding areas. During Phase I of the Air Force 19834-1985 SBIR program, Spectral Sciences, Incorporated investigated the feasibility of developing a man-portable HCl monitor capable of unattended operation. The major Phase I objectives were to experimentally demonstrate a novel infrared light source and to design and HCl monitor, based on the new infrared source, which should be built and field tested in Phase II. The spectral output of the HCl infrared lamp was measured and was found to be consistent with earlier theoretical predictions. This HCl lamp was used in conjunction with a room-temperature HCl absorption cell to demonstrate the potential sensitivity of the approach to measure small ambient HCl concentrations. Even with the relatively crude nature in which the emission-absorption measurements were made, the authors were able to demonstrate detectable absorption down to 2 ppm for a field instrument. With the improved HCl lamp design and the real time self calibrating optical layout presented in this proposal, it is felt that ambient HCl concentrations as low as 0.1 ppm can be detected with the Phase II instrument.
