This new valuable analytical asset provides Johnson Matthey assay services with a number of competitive advantages, including the following capabilities:

  • fire assay for trace – 5% level pgms; nickel sulphite collection, lead collection, cupellation;
  • specific method to assay autocatalyst material;
  • wet chemical precipitation for mid-grade pgms;
  • direct dissolve for high-grade pgms;
  • analysis by XRF for high-grade >75% platinum alloys; X-ray fluorescence;
  • real time data available on samples and their progress to accurately predict ETA for for customers' sample assay resuts.

In addition, there are other analytical techniques available:

  • Induction Coupled Plasma (ICP);
  • Atomic fluorescence;
  • Potentiometric titration;
  • Carbon/sulphur analysis;
  • Thermo-gravimetric analysis (TGA).


Guarantee 
precise precious metal analysis

Our advanced sampling methods and experienced analytical chemists ensure that your samples are assayed with high accuracy. We participate in a unique Round Robin Analysis Programme, where independent laboratories analyse controlled samples. 

We study the total matrix of your material by evaluating both precious metal and non-precious metal content. This analysis allows us to determine the best processing route for your material. As a result, we give you a quote you can rely on.

What do we assay for?

Precious Metals - Au, Ag, Pt, Pd, Ir, Rh, Ru.

Base Metals - Cu, Ni, Pb, Fe, Se, Te, C, S, etc.  

Other elements which may cause problems in our process.
