Abstract

Powder X-ray Diffractometer (XRD) is an analytical device widely used for material characterization in geology, environmental science, material science, biology and mechanical engineering. Traditional XRD systems are powerful tools for material identification, but the design is bulky and requires dedicated space and infrastructure, which limits their flexibility and efficiency. A newly developed portable XRD combines powerful analytical capability with compact design. It is lightweight and portable. The self-developed software provides quick and robust data interpretation. For most samples, over 10,000 counts data can be collected in one minute. Quick phase identification is also possible in just a few seconds. A large amount of data analysis demonstrates the device’s robust working flow and its capability of precise and accurate identification of structures. To support filed applications, we also developed a handheld powder sample drill that extracts fine powder samples from solid materials. Researchers and professionals can now bring both the portable XRD and the sample drill directly to the field or manufacturing sites for immediate material analysis, eliminating the need for transporting samples to a central laboratory. This solution is particularly useful in industries such as energy, oil, gas, and mining, where on-site decision-making based on rapid data collection is critical for operational efficiency.
