The auto sample changer adopts an imported stepper motor drive and a programmable logic controller (PLC) as the core control system. The selection of these two key components significantly ensures the precision, stability, and long-term reliability of the equipment's operation. The workflow of the auto sample changer is designed to be simple and efficient: The operator pre-loads up to six samples sequentially into designated positions of the sample changer. After setting the measurement parameters via the control system, the sample changer begins operation. Following program instructions, it automatically and accurately delivers each sample in sequence to the measurement position of the X-ray diffractometer.Once the measurement of one sample is completed, the device automatically removes it and swiftly delivers the next sample until all samples are measured. Measurement data is automatically saved, facilitating subsequent review and analysis while reducing recording errors that may arise from manual operations.The entire process requires no manual intervention, allowing the operator to free up time for other tasks and avoiding potential fatigue-related errors from prolonged operation. In addition to the basic auto sample changing function, the equipment also boasts several noteworthy features: Efficiency Enhancement: Enables unattended continuous auto measurement, making it particularly suitable for rapid screening of batch samples or sequential analysis over long periods. Data Consistency: The automated process reduces human intervention, helping to improve the repeatability and comparability of measurement data. Ease of Operation: The PLC-based control system is typically stable and user-friendly, lowering the operational threshold. Flexible Application: Primarily used in fields such as environmental protection, electronics/batteries, and other areas requiring material analysis technologies. This auto sample changer primarily serves the application field of X-ray diffraction (XRD) analysis. Dandong Tongda Science and Technology Co., Ltd. has accumulated experience in the field of analytical instruments. Its TD series of analytical instruments and non-destructive testing equipment are applied in various material research fields. This 6-position (or 12-position) auto sample changer reflects the company's approach of integrating automation technology into traditional testing equipment to enhance overall efficiency. As a functional accessory, it works in coordination with X-ray diffractometers, enhancing the automation capabilities of the host instrument.
