Minalyser

Elemental Cross Belt Analyser

The ScanMin Minalyser™ is FAST NEUTRON DUAL GAMMA ACTIVATION ANALYSIS (FNDGAA) Elemental Analyser. The analyser uses a high energy AmBe241 radionuclide neutron source, which irradiates ALL the material on the belt as result of the temporary excitation of the atoms in the material. This provide opportunity to measure two physical reactions:
  • Neutron Inelastic Scatter (NIS)
  • Thermal Neutron Capture (TNS)
The source life is 432 years which ensures no source top up during the lifetime of the analyser. This dramatically reduces the OpEx costs. ScanMin’s patented double decker detector system measures the Gamma Rays emitted by the NIS and TNC reactions above and below the conveyor, compensating for any mass variation on the belt. Each element will have a unique set of Gamma Ray spectrums for NIS and TNC. By selecting Regions of Interest (ROI) the ScanMin team can identify the Element and quantify its concentration.
