Fast, precision XRPD is facilitated by a high-powered rotating anode generator that supplies a high flux of X-rays to two different horizontal-circle powder diffractometers: 185mm Bragg-Brentano diffractometer is optimized for high intensity for fast data collection; 250mm Bragg-Brentano diffractometer is optimized for high resolution at slightly slower data collection speeds. Sample size is generally 20mm x 10mm x 0.3mm, though we have a variety of sample holders and mounting procedures to accommodate varied sample geometries.
