Scanning Materials with Laser Technology


Laser Scanning -- Watch Tutorial Video - See link Below

  • Quality control of bulk materials in many industries (such as mining materials, scrap materials, cement products, construction materials and waste materials) is critical to ensure cost effective processing and downstream product management.
  • Information feedback on the properties of bulk products in near real time with minimal sample preparation can provide a major improvement in production quality control.
  • Our systems make use of a process known as Laser Induced Breakdown Spectroscopy (LIBS). LIBS is a process that employs a high-powered laser to excite the atoms in a target material. This excitation process releases energy in the form of light that can be used to identify the type and properties of the materials analyzed. 
  • The practical patented application developed by CE for this technology is its use in scanning materials and determining the identity and properties of the materials in near real time, with minimal sample preparation.

How Does it Work?

Introduce Sample to Laser Scanning Chamber


Bulk material samples are placed on rotating sample platform in preparation for laser scanning.

Light Collection and Spectrometer Resolution


Light emitted from the excited atoms is transported through optical fibers to a spectrometer for wavelength and intensity resolution.

Signal Resolution and Fingerprint


Collected light is resolved into unique wavelength and intensity patterns that are modeled using multivariate modeling techniques; and these models are subsequently used to identify unknown materials.

Atom Excitation


After the sample is charged into the material feed hopper, the laser is activated. The laser hits the materials flowing through the material flow chute ablation a small mass and releasing light in the process.
