The benchtop powder X-ray instrument is set up to collect PXRD in reflection mode with a 2θ scan range of 3° to 120°. The instrument uses Cu radiation and a wide area scintillation counter detection system. The instrument is operated at the maximum power 600W (40kV – 15mA) and data collection scans can be continuous or step-wise. A variety of sample preparation techniques can be used, and we have three zero background single crystal quartz sample holders. The system is available for wide-angle, powder, and film x-ray diffraction experiments on samples ranging from minerals to macromolecules.
