High-throughput powder X-ray diffractometer
Description
The device will be equipped with a programmable high troughput stage for mounting 24 / 48 / 96 / 192-well rectangular plates. The device will enable rapid recording of a powder diagram in order to analyze a large number of samples (angular range: 1-60° 2θ; acquisition time ≤ 1 h). In addition, the device will be usable in both reflection and transmission. The device will also be equipped with software for phase identification using internal libraries and external databases (such as the open crystallography database, COD).
The device will also enable quasi-quantitative cluster analysis and semi-quantitative data analysis.
