This has led to some confusion regarding which technology to employ and why.
To help decide between XRF and XRT inspection, it helps to understand how each of them works.
Nearly all elements, from iron to copper to nickel to tungsten, have unique and known X-ray signatures.
The right technology makes the difference!
When an X- or Gamma-ray is absorbed by an element, the element fluoresces, or emits energy. Inner-shell atomic fluorescence produces the X-ray signature, and can be "captured" and reported.
XRF analyzers do both tasks: they provide the incident X-rays that generate the excitation in the atoms and then detect the fluorescence from most of the elements in the sample material.
Our XRF is the right technology!
In the recent past, sorting Aluminum alloys by means of XRT (X-ray-Transmission) technology has been tried.
However, this expensive sensor technology (based on the physical property of material density) is not precise
enough for specific alloy sorting.
With our XRF technology we are able to have a feeding process of material at a maximum of 12 lines and up to 10 tons per hour.
