Thermo Scientific GS Omni


GS Omni analyzer for unique light element analysis in slurry process streams.

The Thermo Scientific GS Omni analyzer provides accurate, real-time elemental analysis of multiple slurry streams for both light and heavy elements. Using the Prompt Gamma Neutron Activation Analysis (PGNAA) technique, the GS Omni analyzer has a distinct advantage over analyzers using X-ray fluorescence by being able to directly measure elements lower than calcium on the periodic table. 

Measuring the process, allowing for:

  • Process Control of containment elements 
  • Product grades (minimizes penalty costs) 
  • Recovery
  • Reagent dosage
  • Circuit stability


  • Analyzes a range of elements in: Iron Ore flotation and Iron Ore wet magnetic separation - S, Si and Al 
  • Phosphate flotation - P, Ca and Si as well as various others light element applications in Sulphide Gold and Base Metal flotation.
  • Accepts multiple streams when using an optional multiplexer
  • Factory calibrated for slurry applications


The Thermo Scientific GS (Gamma Slurry) Omni analyzer is the latest development of a proven, robust, analyzer that provides direct simultaneous analysis of multiple elements in slurry beneficiation plants.

The analyzer is available in configurations of 1-8 streams. The optimum number of streams is usually dependent on the stream concentrations, elements of interest, required cycle analysis time, plant layout and process control considerations.

This elemental analyzer will enable improvements in product quality, recovery and lower production costs.


The Thermo Scientific GS Omni analyzer is a powerful measurement tool in the following applications:

  • Slurry beneficiation / Light element analysis 
  • Product quality / Penalty costs
  • Tailings management

Slurries include: 

  • Iron ore
  • Sulphur
  • Phosphates 
  • Copper
  • Calcium carbonate 
  • Magnesium
  • Chlorine
  • Industrial Minerals 
  • Rare Earths
