Rapid Characterization of Soils, Rocks, and Ores with Handheld XRF

Handheld X-ray fluorescence (XRF) analyzers from Olympus offer high performance, real-time geochemical data for fast multi-element characterization of rocks, ores, and soils.

Handheld X-ray fluorescence (XRF) analyzers

Of late, significant developments in XRF technology have immensely enhanced the number of elements measured and limits of detection, as well as drastically decreased analysis test times.

Vanta™ handheld X-ray fluorescence (XRF) analyzers offer expedient, quick measurements of stream sediments, soils, and rock outcrops either in situ or at exploration camps to receive immediate field geochemistry outcomes.

Advantages of Handheld XRF

  • Concentrate on anomalies instantaneously; infill/extension sampling increases productive time in the field
  • Cover large regions very rapidly, increasing sampling density and making decision-making timeframes advance
  • Pre-screening using XRF allows priority sample selection for laboratory analysis, increasing analytical budgets
  • Built-in GPS for quick spatial visualization using GIS
  • Optimization of drilling budgets through informed on-site decision making

Return on Investment

Handheld XRF has currently become a regular tool for soil surveys and regional mapping, particularly for base metal and gold projects. It is now well recognized that million dollar savings are actually possible, provided if appropriate conditions are given. One ASX listed explorer projected savings of $2.75 million over a three-year span. This is a direct result of using three handheld XRF analyzers as the principal tool for testing 100,000 samples during this time period in comparison with the equivalent costs of assaying all these samples at a laboratory.

The graphics to the right show the variation in sample density that can be obtained by this company through conventional sample collection, preparation, and dispatch to a laboratory in comparison with that obtained via direct in situ measurements using XRF. These images illustrate the potential to combine XRF data with GIS and GPS, find out drill targets quickly, and start a follow-up drill program instantly to quickly advance project timeframes.

Olympus IMG and Operating Procedures

In 2008, Olympus launched its dedicated International Mining Group (IMG). This group is an experienced team of geoscientists completely focused only on geological applications of XRD and XRF technology. The IMG is devoted to geological innovation, industry best practice XRF use, and helping the company’s customers to create “fit-for-purpose” technologies that offer important and precise geochemical and mineralogical information about the projects of the customers.

Project conditions differ according to the regional climates, geological setting, and the technical experience of the XRF user. These factors influence the type of XRF methodology devised for individual projects. The global expanse and experience of Olympus will help guarantee that they offer the best product at reasonable pricing as well as exceptional support and service that help increase the customer’s investment in handheld XRF.
