Abstract
A device and method of use are provided for measuring the concentration of fatty acid methyl ester (FAME) in jet fuel to a limit of detection of 1 ppm. The device measures concentration of FAME in jet fuel via Fourier transform infrared spectroscopy (FTIR) with a spectral resolution of 1 cm−1. The device can use an infrared light emitting diode (IR LED) and mercury cadmium telluride (MCT) detector in which the spectral output of the IR LED and the spectral response of the MCT detector is centered on the spectral absorbance of an ester bond, a defining spectral characteristic of FAME. Other IR LEDs with differing spectral outputs can be used to measure the presence and/or concentration of different analytes in different fluids.
