Near-Surface Exploration GeoChemistry

Our near-surface exploration analysis techniques are designed for excellent recovery of base- and trace-elements from regolith materials. These are ideal for products from shallow drilling, such as aircore, rotary-air-blast and auger samples.

Microwave-Assisted Aqua-Regia Extraction
LabWest has developed microwave-assisted digestion techniques to obtain maximum recovery of metals from geochemical samples, with negligible loss of volatiles and no cross-contamination.

Our microwave-assisted aqua-regia digestion (scheme code MAR) is a first-class exploration tool, giving a degree of confidence in results that is not easily obtainable with traditional hotplate or hotbox techniques.

Very low detection limits are obtained with current-generation ICP-MS.

LabWest Code MAR-01 20 elements
LabWest Code MAR-04 44 elements
