TERRA Field XRD Analyzer

High performing, completely contained, battery operated, closed-beam portable XRD that provides full phase ID of major, minor and trace components with a qualitative XRF scan of elements from Ca to U.

Portable XRD/XRF has completely revolutionized geochemical exploration, mine grade control, metallurgical and process analysis, on-site HAZMAT inspections and in-field counterfeit pharmaceutical determinations. The TERRA’s high quality data and speed of analysis delivers quantitative real-time compositional chemistry, right at the point of the sample location, where you need it most.

Initially conceived to perform chemical and mineralogical testing for NASA’s Mars Science Laboratory (MSL) mission, Olympus’ TERRA is a rugged, fully portable field instrument which harnesses advanced dual XRD/XRF technology and renders it for earthbound applications. Combining both Olympus and NASA innovation, TERRA brings to life a new way of performing X-ray diffraction and X-ray fluorescence measurements.
Using a specifically developed direct excitation charge coupled device (CCD) “camera”, TERRA is able to collect X-ray photon data for both X-ray diffraction and X-ray fluorescence simultaneously. This is the result of the integrated camera’s ability to detect both photon position and photon energy at the same time. With energy resolution of ~200 eV (5.9 keV), TERRA makes XRF analysis as simple as viewing the software spectrum display.
Features and benefits:
  • Easy Sample Preparation

TERRA radically simplifies sample collection for your X-ray diffraction experiments. Typically, a sample must be finely ground and pressed into a pellet in order to ensure a sufficiently random orientation of the crystals. TERRA’s patented sample vibration chamber eliminates this issue. Requiring a mere 15 mg sample, the vibration chamber’s convection process presents the instrument optics with multifarious orientations of the crystalline structure. This results in a superb X-ray diffraction pattern, virtually free of the problematic preferred-orientation effects encountered when using classic preparation methods. Due to its unique powder-handling system, nonmechanical goniometers, and lack of complicated moving parts, TERRA is extremely well suited for those applications where field portability and/or ease of use is at issue.

Mining & Ores

  • Iron Ore – Quickly analyze iron rich ore with Xpowder’s Reference Intenstiy Ratios to automatically generate quantitative compositions of the samples even when certain phases are completely absent – quartz, hematite, goethite, magnetite & more
  • Calcite in Coal – Quantify calcite (CaCO3), a mineral identified as reducing the efficiency of the raw material fuel in a coal-fired plant, to improve efficiency and reduce carbon emissions
  • Potash – Analyze potash for phase identification and semiquantitative analysis of identified minerals such as sylvite, halite, langbenite and leonite. For further refinement, Sietronics Siroquant is available
  • Limestone & Cement – Easily perform quantitative analysis of common minerals associated with limestone – alpha-quartz, asbestos minerals, calcite, dolomite and more. In cases where the quarry contains various levels of dolomite, the TERRA quickly determines this mineral in the range of 0.50 to 9.0% with an error of only 0.02%.


  • Mudlogging – Perform mineral ID and quantification on shale cuttings in the field for rapid feedback at drilling sites – simplify “chasing the vein” of a given mineral strata
