:: Terra Portable X-Ray Diffractometer Helps Discover a new Mineral, Cranswickite

The International Mineral Association (IMA) has recently recognized the existence of a new mineral discovered by Dr. Ronald Peterson of Queens University Kingston, Ontario, Canada. Using the field portable X-ray diffractometer, Terra, Dr. Peterson discovered the new mineral during a research trip to Argentina. Quoting Peterson, The identification of the new mineral, cranswickite, and the identification of the associated minerals were made possible by using Terra. All of these hydrated magnesium sulfate minerals are soft white powders and are often mixtures. The ability to distinguish these minerals while conducting field work in the remote mountains of Argentina would not have been possible without a portable X-ray diffractometer. The use of a portable diffractometer on location in the field allowed efficient study of the mineral assemblage without returning to use a laboratory X-ray diffractometer."

Terra is the worlds first X]ray diffraction instrument designed specifically for field applications. Completely contained, Terra allows for remote operation in environments where the advantages of XRD were not previously possible. The Terra is manufactured by InXitu exclusively for distribution by Olympus Innov]X, a world leader in the design, development and distribution of portable analytical instruments.
