EDXRF Proves a Very Useful Tool in Characterizing Recycled Feedstocks

Mar 12 2008 Read 973 Times

Concerns about global warming and potential pollution of scarce resources by runoff from landfills and other retention receptacles are driving recycling of many of our commonly used materials.
Recycled materials are generally composites of the original raw material and additives that were added to give the finished product certain required properties and as such these waste materials coming
from multiple different waste streams would need to be characterized (profiled) in order to ascertain the presence and levels of elements that would need to be removed before reprocessing could occur for any number of reasons.
EDXRF can play a very useful role as a screening tool to identify and quantify elements of interest and to evaluate raw material sources for economic viability of the source as feedstock for a particular product,
identify and quantify levels of elements that could prove deleterious to the process and would mean that the material should be pre-treated
before processing. continuous process monitoring to help with optimization of the process and final quality control of the product or intermediate to make sure that the product specification is maintained.
Jordan Valley (USA) introduces the powerful EX-Cite and EX-Calibur benchtop Energy Dispersive X-ray Fluorescence (EDXRF) spectrometers which enable system operators to identify the elemental composition of up to eight samples in one automated acquisition as the solution to material characterization.
The analyzers deliver rapid, non-destructive, multi-element determinations from ppm to high weight percentages of elements ranging fromsodium( Na) to uranium(U) in samplematrices that include liquids,
solids, slurries, powders, pastes The EX-Cite system utilizes 35kV, 9-watt X-ray technology to analyze samples in a non-destructive manner. This approach is particularly valuable in applications where limited sample integrity must be preserved for further testing.
The 50kV, 50-Watt EX-Calibur delivers performance capabilities similar to traditional liquid nitrogencooled detector units by achieving similar resolution to an LN2 cooled Si(Li) detector. Close coupled geometry, full power excitation with highly tunable energy levels allow the Ex-calibur to deliver great sensitivity and selectivity in one compact footprint analyser.
The robust design and build of the EX-Cite and EX-Calibur allow them to meet MIL810E shock resistance certification and the space-saving form means that the unit is ideally suited for mobile lab or plant lab applications.
The markets served by Jordan Valley also include chemical, cement industry, personal care and pharmaceutical products, the petroleum industry, mining and mineral industry for process and quality control.
