Portable XRD Analyzers

The TERRA Mobile XRD System, a high performing, completely contained, battery operated, closed-beam portable XRD, provides full phase ID of major, minor and trace components with a qualitative XRF scan of elements Ca - U. Its unique, minimal sample prep technique and sample chamber allow for fast, in-field analysis.


Patented Technology From NASA and Olympus

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.

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.

XPowder Software

TERRA is shipped with the necessary software (XPowder) for processing the resulting X-ray diffraction data. This includes the AMSCD mineral database.

For quantitative analysis, XPowder comes complete with reference intensity ratio (RIR) quantitative analysis methods as well as full-pattern analysis tools.

Furthermore, TERRA provides XRD pattern data in a variety of file formats, making XRD pattern interpretation in third-party programs easily accessible.

XPowder Software


TERRA operates off software embedded in the unit itself. The user accesses the operating system through a wireless connection (802.11b/g). This remote operation method allows for a wide degree of flexibility in controlling the instrument and subsequent data handling.

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.

Mining & Ores

  • 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%.
