Automatic XRD Sample Preparation Platform
Automatic XRD Sample Preparation Platform
Automatic XRD Sample Preparation Platform
The complete XRD sample pretreatment workflow supports two loading modes: a powder workflow (which includes cap opening, aspiration, surface leveling, and sample feeding for testing) and a suspension workflow (involving liquid dispensing, ultrasonic homogenization, leveling, and sample feeding for testing). Traditionally, capping, sampling, sample preparation, and loading are heavily reliant on manual operation, creating a bottleneck for throughput and consistency in XRD pretreatment. Equipped with a collaborative six-axis robotic arm, this platform achieves full-process automatic pretreatment and forms a closed loop connected to the XRD detector.
Features
- Flexible Dual Modes
Two integrated loading workflows are available for powder and suspension samples. Timing control optimizes overall efficiency.
- Integrated Automation
Force-feedback scraper jaws level and compact powder with controllable pressure. Intra-batch consistency is maintained with a coefficient of variation (CV) less than 5%.
- Visual Inspection
An industrial camera evaluates surface flatness, thickness uniformity, bubbles, and position offset. Defective samples are rejected for rework before testing, reducing the invalid test rate by over 80%.
- Expandable Vision & Communication
A standard API supports TCP/IP and Modbus protocols, establishing an intelligent closed loop of "sample preparation – measurement – optimization."
