In recent decades, a significant leap in geochemistry has been the ability to gather geochemical and mineralogical data directly in the field during geological investigations. Among the most impactful advancements in this realm is the utilization of X-ray fluorescence spectrometry (XRF), offering near-real-time elemental analysis of geological materials outside conventional laboratory settings.

Portable handheld XRF analyzers have revolutionized various fields including geology, mineral exploration, soil science, and environmental monitoring. Their versatility and efficiency have made them indispensable tools across the geosciences.

Applications in Geology and Mining for Handheld XRF

Core Analysis for Exploration Drilling

Mineral Exploration

Geochemical Testing and Mapping

Mine Face or Pit-Face Analysis

Waste Processing and Metal Recovery

Ore Grade Control

Silver Ore Mining

Mineral Lab Alternatives

Handheld XRF technology enables basic geochemical analyses during field mapping exercises, with results comparable to laboratory XRF analyses for most elements, albeit with slightly lower precision. Quick measurements on fresh outcrop surfaces typically take about 60 seconds, aiding lithologic correlations during fieldwork.

On-site sample preparation, like breaking and smoothing fresh surfaces, can enhance the precision and accuracy of handheld XRF analyzer results. These data are invaluable for selecting samples for further geochemical or geochronological analysis, optimizing fieldwork efficiency.

Advantages of Handheld XRF Analyzers in Geology Compared to Lab Analyzers

While laboratory analyses offer the highest quality data, they often come with significant costs and time requirements for sample preparation and analysis. Handheld XRF analyzers fill a crucial niche by providing rapid, in situ data, streamlining field operations, and aiding in sample triage for subsequent laboratory work.

Why Terra Series Handheld XRF Analyzers are Ideal for Geology

The Terra Scientific Handheld XRF facilitates on-site geochemical analysis of mine faces, drill cores, or prepared samples. Real-time analysis with this device significantly reduces turnaround times, from days to seconds compared to laboratory analyses, enhancing productivity and decision-making in mining operations.

Additional advantages of the Terra Series handheld XRF analyzer include

(a) Portability and ease of on-site use

(b) Minimal sample preparation required for non-destructive testing

(c) Short detection time and reliable quantitative analysis results

Equipped with a high-performance X-ray tube and Si-Pin/SDD detector, the Terra series ensures fast and accurate element concentration analysis. An optional large-area silicon drift detector further enhances instrument resolution and reduces analysis time, providing a comprehensive solution for quality monitoring and safety compliance testing in mining environments.
