Exploration Geochemistry

Genalysis Intertek offers a variety of multi-element analytical techniques to meet the geochemical requirements of the exploration community.

A diverse array of sample decomposition techniques used in conjunction with a number of sophisticated instrumental finishes, ensures that the correct fit- for- purpose method with the requisite detection limits is available.

Sample Decomposition:

One of the first considerations in choosing an exploration method is the decomposition technique to be employed. Sample decomposition techniques include acid digestion and fusions, as follows:

• Aqua Regia Digestion
• Single and Multi-Acid Digestions
• Sodium Peroxide Fusion and Lithium Metaborate Fusion

Testing Instrumentation:

The most commonly used instruments are ICPOES, ICPMS, AAS and XRF.

ICPOES and ICPMS are widely used because of their convenient, virtually simultaneous multi-element capabilities.

AAS is generally used where single element work or a small number of elements are required.

XRF pressed powder is routinely used for trace element analysis in exploration samples while XRF fused bead is applied to major element analysis.

Other Geochemical Analysis options include:

• Carbon and Sulphur by Induction Furnace - Infrared
• Partial Digest, Selective Leach Geochemistry
• Analysis of Biogeochemical Samples, Biota and Plant Tissue
• Whole Rock Geochemistry
