Area of Science:

• Materials Science
• Analytical Chemistry
• Synchrotron Radiation

Background:

• Automated sample handling is crucial for high-throughput analysis in materials science.
• X-ray diffraction (XRD) is a powerful technique for material characterization.
• Current methods for XRD sample preparation and analysis can be time-consuming.

Purpose of the Study:

• To design, construct, and automate a novel system for XRD measurements in reflection geometry.
• To improve the efficiency and reproducibility of sample loading, alignment, and data acquisition.
• To enable high-throughput analysis of solid oxide electrolysis button cells (SOECs) and other sample types.

Main Methods:

• Development of a single-platform system with compartmentalized sample storage, transfer, and positioning.
• Integration of a six-axis robotic arm for precise and programmable sample manipulation.
• Utilization of 3D printed sample mounts and cassettes for flexible sample accommodation (up to 84 samples).

Main Results:

• The automated system demonstrated facile transferability and adaptability to various beamline environments.
• The robotic arm enabled highly reproducible movements for precise sample alignment.
• The system processed up to 84 SOEC samples in approximately 24 hours, including long exposure scans.

Conclusions:
