![]() Improved by tailoring their shape to the shape of gratings. Bad spectral resolution of MIM noted earlier is now Mirrors (MIM) for detection and quantification of very light elements. WD-XRF is continuously improved, by applying new multilayer interference Than other simpler instrumental or wet techniques. In routine geological and environmental analyses, the WD-XRF performs better Which can be amortized only in routine operations. System with sequential analysis of particular elements, low output of energy supplied to the device, and great cost of instrument Among the drawbacks, the following are important: Peak shape which gives the basis for the chemical speciation are the advantages. In a range below 5 keV, good operational stability, excellent ability of making averaged analysis, and good presentation of Wavelength-dispersive X-ray fluorescence can be characterized by its advantages and drawbacks.
