Terra II portable XRD analyzer
The world's first battery powered commercial portable XRD analyzer is replaced by the TERRA II analyzer, which is equipped with a windproof, rainproof, and durable housing. Powered by batteries, it can work continuously for up to 6 hours, allowing for mineral detection and analysis in outdoor environments, providing users with quick information on the main and secondary components of minerals.
The TERRA II analyzer provides powerful features that can replace traditional XRD instruments, is lightweight, easy to carry, and requires almost no maintenance.
Equipped with a unique small sample holder, analysis can be completed with only 15 mg of sample
No external power supply, compressed gas, water cooling device, secondary chiller unit, or external transformer is required for operation, thus maintaining a low cost of ownership
Through wireless connectivity, the analyzer can be connected to your device
The SwiftMin software used by the analyzer is simple and intuitive, with the following features: a single screen control panel displaying multiple data, pre-set calibration programs, easy data export, and automatic data transmission, thereby simplifying the user's workflow

The improvement of speed and sensitivity helps users make quick decisions
The TERRA II analyzer combines powerful, concise, and intuitive software with an improved X-ray detector, which not only enhances sensitivity and speeds up the analysis process, but also provides more reliable results.
The updated X-ray detector hardware runs faster and has higher analysis density, resulting in lower detection limits (LOD).
SwiftMin automatic mineral phase identification (ID) and quantification software can provide real-time data directly on the XRD analyzer, so users can make decisions quickly, timely, and confidently

Easily complete the preparation of samples
Traditional XRD instruments require grinding large quantities of samples into powder and then rolling them into small spherical shapes to ensure sufficient random orientation of the grains.
In contrast, the TERRA II analyzer can use a small vibrating sample holder to induce convection of all particles in the sample chamber, ensuring that the data is almost unaffected by directional effects. Therefore, the instrument only requires 15 milligrams of sample to obtain high-quality detection results, and operators can easily prepare samples using the sample toolkit provided with the instrument.

SwiftMin's automatic mineral phase identification (ID) and quantification software can provide real-time data directly on the XRD analyzer, allowing users to make decisions quickly, promptly, and with confidence. When performing repetitive detection operations, the intuitive and concise functions of SwiftMin software can improve efficiency and save time. The software performance is as follows:
Multiple data displays on a single screen control panel: allowing users to view all mineral composition, calibration, and analysis information on the same screen, thereby speeding up workflow.
Pre set calibration program: By using a password protected new laboratory administrator screen, preset calibration modes can be entered, allowing operators of any level to use the analyzer and quickly obtain reliable results.
Automatic data transmission: When the operator clicks the "stop" button or after a preset period of time, the analyzer will automatically send data to the user's network.
Easy data export: Users can easily export quantitative mineralogical results for viewing or further data analysis. They can also access raw data files through network folders to analyze diffraction patterns.

Advantages and Characteristics of Olympus XRD Analyzer
Convenient sample preparation: Traditional desktop XRD instruments generally require testing personnel to perform a large amount of sample collection and preparation work, as large quantities of samples must be ground into powder and carefully rolled into small spherical shapes. If the sample is ground too finely or the compaction force is too strong, it may cause sample preparation effects, such as preferential orientation issues. However, Olympus' XRD analyzer is different in that it only requires 15 milligrams of sample to obtain high-quality detection results, and the testing personnel can easily prepare samples using the sample kit provided with the instrument.
Simultaneous measurement: Traditional desktop XRD instruments require several seconds to obtain each 2-theta measurement value, so obtaining all 2-theta measurements may take up to several hours. The Olympus XRD analyzer is equipped with a charge coupled device (CCD) detector, which can simultaneously obtain all 2-theta measurement values, making it possible to display the complete diffraction pattern almost immediately on the screen.
2D X-ray diffractometer: Many XRD tools use X-ray detectors that can only capture photons that fall off the sample in one plane, completing one-dimensional experiments. Olympus' XRD analyzer equipped with a charge coupled device (CCD) detector can collect slices of diffraction rings to help users understand whether the sample has been prepared correctly (particle statistics and/or preferred orientation of grains). Based on this information, users can confirm the accuracy and representativeness of the quantitative data obtained.
Perspective geometry: Unlike large traditional XRD instruments that use reflection geometry techniques, Olympus' XRD analyzer uses transmission geometry techniques at the location where the X-ray beam passes through the sample. The sample volume in the sample pool remains fixed, so changes in sample density will not affect resolution. This feature is particularly important for low-density materials, such as drug samples. Compared to instruments based on reflective geometry technology, our instrument can achieve higher resolution with fixed penetration performance.
Energy differentiated X-ray detector: Larger traditional desktop XRD instruments generally cannot use detectors that are more sensitive to energy, so the detector will be affected by photons that are not used in XRD experiments. In contrast, Olympus' XRD analyzer can remove photons that are not directly involved in X-ray diffraction experiments, such as X-ray fluorescence photons, thereby providing better signal-to-noise ratio modes.
Cobalt tube and copper tube options: The Olympus XRD analyzer comes standard with a sturdy and durable cobalt (Co) target X-ray tube. This type of anode ray tube is widely favored by geologists and mineralogists because it can perform excellently in analyzing samples with high iron (Fe) content. However, in certain applications (such as high manganese content in samples), copper (Cu) target X-ray tubes are required. According to the specific application needs of users, Olympus can provide either of these two types of anode target X-ray tubes.

Olympus instruments use transmission geometry techniques (as shown in the above figure) instead of the reflection geometry techniques used in traditional XRD instruments based on angle measuring instruments. The instrument does not have moving parts, but achieves randomization of sample detection through the use of a unique vibrating sample tray. The instrument uses a constant frequency to randomize powder samples, which is called powder liquefaction.
The powder is placed between two polyester or polyimide film windows, as shown in the following figure.

Thanks to our convection technology, every grain of the sample in the sample chamber will be irradiated with an X-ray beam in every possible direction within 30 seconds. Through this method, Olympus XRD instruments can achieve 100% randomization of sample detection, which is also a key factor for accurate and precise X-ray diffraction analysis. The Olympus XRD analyzer only requires 15 milligrams of sample to simultaneously collect all practical 2-theta measurement data. The absence of moving parts also contributes to the reliable performance and almost maintenance free advantage of our XRD analyzer.
