Advanced technologies for identifying metals and alloys in recycling operations

When the exact chemical composition of scrap—including the existence of contaminants or hazardous elements—is uncertain, it puts quality, safety, and regulatory compliance at risk. Analytical technologies can play a crucial role in making recycling more efficient, cost-effective, and safe. Scrap metal recyclers use XRF and LIBS technologies to verify elements of interest in virtually all types of metal alloys, from trace levels to commercially pure metals. LIBS analyzers are suited for low alloy steel and stainless steel sorting based on their carbon content, and support the increase in the value of stainless-steel sorting by helping to separate SS-316 from SS-316L. 

 

Additionally, XRF analyzers can help identify and separate potentially hazardous materials, such as lead and mercury, ensuring proper disposal and reducing environmental hazards. Radiation detection and monitoring technologies can help prevent contaminated scrap from entering the supply stream.


X-ray fluorescence (XRF)

X-ray fluorescence (XRF) spectroscopy is a nondestructive analytical technique used to determine the elemental composition of materials. XRF analyzers work by measuring the fluorescent (or secondary) X-rays emitted from a sample getting irradiated by a primary X-ray source. Each of the elements present in a sample produces a set of characteristic fluorescent X-ray lines like a fingerprint.  These fingerprints are distinct for each element, making XRF spectroscopy an excellent tool not only for qualitative analysis but also for quantitative measurements when processing the intensity of the emitted lines. XRF allows users to rapidly identify and confidently grade aluminum and magnesium alloys, as well as high-value alloy families such as stainless steel, nickel, cobalt, and titanium.

This high value analyzer is ruggedly built to withstand the harshest environments.

Laser induced breakdown spectroscopy (LIBS)

Laser induced breakdown spectroscopy (LIBS) is an analytical technique that uses a laser to determine the chemical composition of materials.  Handheld LIBS analyzers work by using a high-focused laser to ablate the surface of a sample. A plasma is formed consisting of electronically excited atoms and ions. As these atoms decay back into their ground states, they emit characteristic wavelengths of light, or “unique fingerprints”. These “fingerprints” are distinct for each element, making handheld LIBS analysis an excellent tool for quantitative and qualitative measurements -- especially for low alloy/carbon steels and L and H grade steels. 

Niton Apollo Handheld LIBS Analyzer

This analyzer replaces a traditional cart-mounted optical emission spectroscopy (OES) system with a highly portable, easy-to-use handheld analyzer.

Radiation monitoring and detection

Our radiation detection technology includes portal monitoring systems for incoming raw materials and portable devices to help keep contaminated scrap out of your operations.

 

Handheld radiation detection devices provide real time detection of gamma radiation with accurate dose rate measurements to verify the radioactive find, and assess whether radioactivity is of natural or artificial (man-made) origin. Portable devices with high sensitivity neutron response and alarm threshold can be worn to monitor gamma sensitivity and energy compensated dose rate measurement.
