A computer-implemented method for determining a water treatment parameter includes receiving, by a computer, measurements of a fluorescence emission spectrum of a water sample including a first peak emission wavelength and at least a second peak emission wavelength, emitted in response to an excitation wavelength, receiving, by the computer, an absorbance measurement obtained at the excitation wavelength of the water sample, determining, using the computer, a ratio of the measurements at either the second peak emission wavelength, or a sum of measurements at a plurality of peak emission wavelengths including at least the first peak emission wavelength and the second peak emission wavelength, to the first peak emission wavelength, and calculating, using the computer, a value for the water treatment parameter based on a combination of at least the ratio and the absorbance measurement.
摘要:
Periodic spatial patterns of x-ray illumination are used to gather information about periodic objects. The structured illumination may be created using the interaction of a coherent or partially coherent x-ray source with a beam splitting grating to create a Talbot interference pattern with periodic structure. The object having periodic structures to be measured is then placed into the structured illumination, and the ensemble of signals from the multiple illumination spots is analyzed to determine various properties of the object and its structures. Applications to x-ray absorption/transmission, small angle x-ray scattering, x-ray fluorescence, x-ray reflectance, and x-ray diffraction are all possible using the method of the invention.
