What Is Wavelength Dispersive X-ray Fluorescence?
The WDXRF X-ray technique employs a high-power X-ray source to excite the characteristic (fluorescence) X-rays from the elements in a specimen.
The defining aspect of a WDXRF spectrometer is the use of a (physical) crystal to achieve energy resolution. Higher energy resolution can minimize or eliminate peak overlap issues.
A sequential spectrometer measures elements of interest one at a time with the automatic adjustment of crystals and X-ray optics. Sequential spectrometers offer analytical flexibility in process R&D and low-volume, high-product-mix manufacturing environments where measurement throughput is not of primary concern.
A simultaneous spectrometer is configured with multiple, dedicated channels to maximize measurement throughput in high-volume manufacturing environments where the elements of interest are not likely to change frequently.
