Wavelength Dispersive X-Ray Fluorescence
For elemental analysis, we are equipped with a Wavelength Dispersive X-Ray Fluorescence Spectrometer (WDXRF). Analyser crystals provide the energy resolution, enabling a high sensitivity (low background) and avoiding the line overlaps which are commonly seen in Energy Dispersive (EDXRF) and associated electron microscopy techniques.
With a high-power 4 kW tube, we are able to measure elemental compositions down to .ppm levels from boron to curium for solids, powers, liquids, thin films and alloys. Our instrument is also equipped with small-spot mapping system, which allows for a particular area of a sample (as small as 0.5mm dia) to be identified using a camera, and then analysed.
For enquiries, please contact our XRF specialist, Chris Waldron, or the facility manager, David Walker.
We also have sample preparation capability and can produce pressed-pellets, and fused beads using our Fluxana Vitreox fusion machine, allowing for sample homogenization and thus more accurate results. To complement this, we have three Fluxana calibration standard sets () for fully quantitative analysis of cements and other raw materials.
Fused bead preparation: Left, sample entering furnace, right: finished bead (in this case, a slag sample)
25t sample press, and finished pressed pellet (a soil sample for trace metal analysis)
