MultiElement Analysis For Whole Rock And LithoGeoChemistry
Our whole-rock analysis techniques are designed for total recovery of rock-forming and refractory materials. Excellent detection limits can be attained by coupling microwave-assisted, HF-based digestion with state-of-the-art ICP-MS determination.
Microwave Assisted Total Digestion
Rudaki Lab’s microwave-assisted total digestion gives lower detection limits and higher recovery of metals than traditional techniques. This leads to a cost-effective, sensitive solution for lithogeochem and exploration purposes that require a broad-spectrum, high recovery analysis.

Alkaline Fusion
Where total recovery of highly refractory species (eg. Zr, Ta, Nb, Hf minerals) or silica is essential, an alkaline fusion technique is recommended. The pulverised sample is fused with an alkaline salt at high temperature then dissolved in acid. Elemental determination is performed using ICP-OES and ICP-MS to give low detection limits and complete recoveries for major oxides, resistate traces and Rare Earth Elements.
