Recycling Assistance has a “Handheld XRF Analyzer” at its disposal: a device that enables fast, on-site and non-destructive chemical elemental analysis up to ppm-level. The XRF Analyzer can i.a. be used to identify lead in paints, for soil analysis and environmental remediation (e.g. tracking residues of zinc ashes), to characterise mineral construction and demolition waste products for recycling (e.g. mineral wool) and to identify ferrous and non-ferrous alloys in scrap.
On-site XRF analysis
What is XRF?
XRF (X-Ray Fluorescence) relies on the fact that a material that is exposed to incoming X-ray radiation sends out characteristic secondary X-rays (fluorescence), with a wavelength determined by the chemical elements that are present in the material. As such, the chemical composition of unknown samples can be mapped. Read more about the basic principles of XRF here.
