Abstract : The U.S. Army has a need for analytical instrumentation that can assess the quality of fuels and lubricants both in the field and in near-the-battlefield conditions. Near-infrared (NIR) spectroscopy was identified as one analytical technique with the potential to meet the Army's requirements. The Army initiated a program to rigorously evaluate the feasibility of using NIR in the analysis of diesel fuels. For this program, the Army specified the use of acousto-optic tunable filter (AOTF)-based NIR instruments. Fuel samples totaling 427 were collected and analyzed for several common fuel properties. Three AOTF-NIR spectrometers were evaluated, and an additional six instruments were purchased based on the initial evaluation. This report presents the results of the fuel analyses and the instrument evaluations.
