Geological Exploration (for Soils, Sediments, Rocks and Drill Core)

An inexpensive package that is useful for geochemical exploration, it provides total analysis where elements are activated even when they are in the most refractory minerals. The method does not require fine pulverising and is therefore less vulnerable to loss of gold onto pulveriser surfaces or sample loss. This is an extremely sensitive (low ppb to low ppm range) trace method but it is not just a trace element technique since NAA is also capable of reporting at per cent levels.

The Value of Independent Analysis

"Neutron Acitivation Analysis is based on physical processes and can provide an independent analysis for confirmation or verification."
