TERRA™ II Portable XRD AnalyzerThe successor to the world's first commercial battery-operated, portable XRD, the TERRA II analyzer has a battery life up to six hours and a rugged, weatherproof case for fast in-field analysis of major and minor mineral components. The TERRA II analyzer offers powerful features that make it a portable, lightweight, and virtually maintenance-free alternative to conventional XRD.

Easy Sample PrepConventional XRD instruments require a large batch of sample to be finely ground and pressed into a pellet to ensure a sufficiently random orientation of the crystals. In contrast, the TERRA II analyzer’s small vibrating sample holder convects all particles within the sample chamber, ensuring that data is virtually free of orientation effects. As a result, only 15 mg of sample is required, easily obtained using the supplied sample kit. | ![]() |

Olympus XRD
How Olympus XRD WorksThe Olympus XRD diffractometers use a unique method to rapidly and easily collect and process XRD data.
Our instruments use transmission geometry (represented in the image above), rather than reflection geometry used in conventional goniometer-based XRD models. With no moving parts, we achieve randomization using a unique vibrating sample holder. It generates a constant frequency that randomizes the powder, known as powder liquefaction. The powder sits in between two windows of either Mylar or Kapton, as shown in the image below. ![]() Thanks to our convective technique, every grain of sample in the chamber passes through the X-ray beam in every possible orientation within 30 seconds. With this method, Olympus XRD tools achieve 100% randomization, a critical component of precise and accurate X-ray diffraction. Requiring a mere 15 mg of sample, Olympus XRD can simultaneously collect the entire practical 2-theta range. The lack of moving parts also makes our XRD products reliable and virtually maintenance free. |
