Apparatus and method for measuring concentrations of fuel mixtures using depth-resolved laser-induced fluorescence

摘要: The apparatus for measuring concentrations of fuel mixtures using depth-resolved laser-induced fluorescence is a fluorometer equipped with sample container holder that movable in the path beam from light source. Fluorescent emissions mixture pass at 90° to excitation through slit narrow enough emission intensity effectively produced by thin layer and focused on monochromator, successive layers receiving nonuniform radiation due reduction along source increasing depth penetration reabsorption emitted adjacent layers. method has first mode which spectrum scanned fixed depth, second moved relative monochromator vary while keeping wavelength fixed.
