Spectroscopic system and method for analysis in harsh, changing environments |
| abstract |
An ultraviolet spectroscopic system and method is described that allows accurate, real-time, analysis of an ultraviolet absorbing gas species (e.g., nitric oxide) in vehicle exhaust independent of the air/fuel ratio (i.e., changing hydrocarbon concentrations). The method, which accurately accounts for the continuously changing background, allows the gas species to be measured selectively and accurately in undiluted vehicle exhaust with portable hardware that can be used on-board a vehicle. |
