We offer a series of thin metal foils and large-area x-ray fluorescence filters for XAFS measurement. The foils are to be used as energy calibration standards for monochromators and as reference materials to extract experimental metal-metal phase shifts and amplitudes for quantitative analysis. The filters are to be used in conjunction with the Lytle detector for EXAFS measurements in dilute systems in the fluorescence mode. The basic function of the filter is to minimize the unwanted elastic and inelastic scatterings from the specimen during the scan and to maximize the fluorescence signal of interest.
