Aqua Regia With ICP-MS Finish
Method selection can be key to achieving exploration success. Sample type, target commodity, and pathfinder elements should all be considered when selecting the most appropriate method for your project. Aqua regia is an excellent exploration tool for various deposit types that involve gold, silver and base metals hosted in sulfide and carbonate minerals.

Single Elements by Aqua Regia
When analytical results for one or only a few elements with low detection limits are required. More elements are available on request.

Aqua Regia With ICP-AES Finish
These methods are economical tools for first pass exploration geochemistry. Data reported from an aqua regia digestion should be considered as representing only the leachable portion of the particular analyte.

Four Acid Digestion With ICP-AES Finish
Four acid digestions are able to dissolve most minerals, but although the term “near-total” is used, not all elements are quantitatively extracted in some sample matrices.

Resistive Elements By Fusion
The lithium borate fusion & ICP-MS finish allows analysis of the most resistive elements at trace levels. Additional elements are available on request.

Halogens
Elemental analysis of the halide minerals containing chlorine and fluorine generally require fusions that will retain the elements in solution, as well as specific instrumentation for analysis.

Mercury
Aqua regia quantitatively dissolves Hg and uses a temperature of digestion low enough to avoid fuming off this volatile element.

Loss On Ignition
LOI measures the content of a sample lost as gases when subjected to high temperatures, often including water and CO2. Many more temperatures and ignition times are available, please enquire.

Conductivity, pH and Acid Insolubles
These methods provide crucial information for mineral processing and environmental assessment studies.

Four Acid Digestion With ICP-MS Finish
Four acid digestion quantitatively dissolves nearly all minerals in the majority of geological materials. However, barite, rare earth oxides, columbite-tantalite, and titanium, tin and tungsten minerals may not be fully digested. Despite the potentially incomplete digestion of REEs, the leachable portion of these elements may hold important exploration vectoring information and can be chosen as an add-on.

Intermediate Level Aqua Regia
These packages can be used as an economical alternative to analyzing low grade ore or samples with known mineralization. Data reported from an aqua regia digestion should be considered as representing only the leachable portion of the particular analyte.

Intermediate Level Four Acid Digestion
These packages can be used as an economical alternative to analyzing low grade ore or samples with known mineralization. Four acid digestions are able to dissolve most minerals, but not all elements are quantitatively extracted in some samples.

Single Elements by Pressed Pellet XRF
Pressed pellet XRF is suitable for determining elements not easily solubilized by acid digestion, but may be subject to interferences due particle size and mineralogy.

Portable XRF For Indicative Analysis
Portable XRF may be used to screen large volumes of samples for intermediate to ore grade elements when the standard lab test is relatively costly and time-consuming. The pXRF method must be calibrated for a specific sample suite on an individual project basis. Submitting samples not represented in the calibration suite creates a high risk of inaccurate results, including false positives. ALS offers custom calibration for pXRF on project-specific sample suites, with our rigorous quality standards and XRF expertise ensuring accurate, reliable results. The pXRF instrument can be located in the prep lab nearest your project, or on-site if the project is remote. Contact your local client sevices team for more information.

Geochronology
These methods may be used to date the ages of specific minerals, hydrothermal alteration events, and emplacement of volcanic-plutonic units. Age constraints on important events can help refine the deposit model and identify alteration that did not contribute to mineralization.
