| Abstract |
An initial evaluation was made of a prototype Fourier transform infrared spectrometer on its ability to measure mobile source emissions. This prototype represents the commercialization of research technology developed by the Ford Motor Co. The system utilizes a Mattson Instruments Co. interferometer coupled to a Masscomp computer. The required software is still incomplete. This has resulted in the inability to correct errors or optimize results. Unreliability of both hardware and software has been a major shortcoming of the system. When operating properly, the system measures carbon dioxide, nitric oxide, and formaldehyde accurately, both when compared to bag analysis and on direct point-by-point comparisons with real-time data. Completion of the evaluation awaits the final software translations and improvements in reliability. |
