Automation systems for OES and XRF

Importance of Automated OES and XRF Analysis

Automated optical emission spectroscopy (OES) and X-ray fluorescence (XRF) systems have become essential in modern metals and mining industries for ensuring consistent quality control, reducing human error, and increasing throughput. By integrating sample preparation, instrumentation, and data management, these systems support rapid and reliable decision making in production environments.

Aims and Overview of the Solution

Thermo Scientific developed the SMS series of automation systems to address the need for end-to-end analytical workflows spanning entry-level to fully integrated laboratories. Key objectives include:

• Eliminating operator variability and subjective influences
• Enhancing reproducibility and traceability through multitasking operations
• Adapting to diverse production scales from smelters to steelworks

Methodology and Instrumentation

The SMS platform integrates:

• Robotic sample handling (circular Omega and XY magazines)
• Automated sample preparation modules (presses, grinders)
• Optical emission (OES) and XRF spectrometers (e.g., ARL ispark, ARL PERFORM’X, ARL 9900, ARL OPTIM’X)
• Modular software for data acquisition, instrument control, and result management
• In-situ “lab in a box” configurations (QuantoShelter)

Key Results and Discussion

Implementations worldwide demonstrate increased sample throughput (over 1,000 samples per day), improved uptime, and consistent analytical performance. Automated performance checks and time-stamped records bolster traceability and reduce scrap rates. Field-portable cabins enable near-real-time process monitoring without extensive infrastructure.

Benefits and Practical Applications

Automation delivers:

• Higher productivity and faster response times
• Reduced labor costs and operator training requirements
• Enhanced data integrity and compliance with ISO 9000 standards
• Scalability across laboratory and on-line process control scenarios

Future Trends and Opportunities

Emerging developments include integration with IoT and Industry 4.0 frameworks, AI-driven diagnostics, remote monitoring, and predictive maintenance. Expanding compatibility with diverse spectrometer models and customizable software modules will further future-proof investments.
