WDX analysis requires minimum or no sample pre-treatment, contrary to ICP or AAS analysis which requires meticulous sample pre-treatments. For example, grind a solid sample to homogenize the compound. Quantitation is possible in the absence of a standard. This is accomplished using theoretical approximation.

Features Highlight

        • Uses x-ray source to irradiate sample that emits fluorescent x-rays (characteristic of the material) to identify an unknown sample.
        • Allows the use of theoretical method to estimate the concentration of materials, if a standard is not available.
        • Have better resolution several times over EDX spectrometers as it uses crystals to diffract the wavelengths of fluorescent X-rays before they reach detectors.
