The TERRA Portable Bench-top XRD Analyser is a high performing, completely contained, battery operated, closed-beam system. It provides full phase ID of major, minor and trace components with a qualitative XRF scan of elements Ca - U. The unit offers minimal sample preparation and sample chamber allow for fast, in-field analysis. With rugged design and long battery-life, it is especially suitable for field work, mining activities, corrosion investigation etc.
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.
Terra XRD sample vibration chamber needs only 10~15 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.
