Intertek INAA (34 elements)



The samples were analysed for 34 elements by instrumental neutron activation analysis.  The analyses were done by Intertek Testing Services in Val-D'Or, Quebec.

Distinguishing characteristics:

  • Au detection limit: 2 ppb
  • Cd detection limit: 5 ppm
  • Ir detection limit: 50 ppb
  • Ni detection limit: 10 ppm
  • Rb detection limit: 5 ppm

 

General Methodology:

The geochemistry of sediment samples was determined with INAA (Instrumental Activation Analysis), by Intertek Testing Services, Val-D'Or Quebec, for 34 trace elements. The silt-plus-clay fraction was used in each analysis. The anaytical precision of the INAA was assessed using laboratory duplicates. The results are consistent but occasional discrepancies arise when dealing with trace amounts. The accuracy of the technique was determined by submitting a standard reference till with each batch to be analyzed. In this case a GSC 'in house' till standard (TCA8010) was submitted.
