MATRIX-F II FT-NIR PROCESS SPECTROMETER

Importance of the Topic

Near-infrared (NIR) spectroscopy has emerged as an essential tool for inline process monitoring and control in chemical, petrochemical, pharmaceutical, polymer and food industries. By providing rapid, non-destructive, multi-component analysis, FT-NIR enables real-time insights into reaction progress, blend composition and quality attributes directly at the point of production.

Objectives and Overview of the Article

This article presents the design, capabilities and applications of the MATRIX-F II FT-NIR process spectrometer. It reviews how fiber-optic coupling, rugged hardware, and advanced software solutions integrate to move quality control from the laboratory to the production line. Key aspects include system configuration, operation modes for contact and contactless measurements, and deployment in hazardous environments.

Methodology and Instrumentation

The MATRIX-F II employs Fourier transform NIR technology combined with up to six fiber-optic probes or sensor heads. Measurement modes include diffuse reflectance, transflectance and transmission, supporting liquid, solid and suspension analysis. An optional 6-port internal multiplexer allows sequential sampling at multiple process points. The system can be installed remotely via fiber optics and housed in temperature- and humidity-controlled analyzer cabinets. For hazardous zones, ATEX/IECEx certified versions and pressurized housings ensure safe operation. Primary accessories include immersion probes, flow cells and contactless sensor heads, all engineered for reproducible path lengths and easy calibration transfer.

Main Results and Discussion

Implementation of MATRIX-F II units across various industries has demonstrated:

• Accurate inline quantification of moisture, fat, protein, octane numbers and polymer properties within seconds.
• Reduced off-specification batches and rework by shifting end-point analysis into the process stream.
• Stable performance and low maintenance due to a robust interferometer design and solid-state laser source with a 10-year warranty.
• Seamless integration with distributed control systems via CMET software, supporting OPC, Modbus, Profibus and analog I/O for automated data exchange.

Benefits and Practical Applications of the Method

Online FT-NIR using the MATRIX-F II enables manufacturers to optimize raw material usage, minimize energy consumption, and ensure continuous product quality in processes such as polymerization, spray drying, oil extraction, fermentation and tablet coating. The contactless sensor head further expands usage to conveyor belts, viewing windows and hard-to-reach zones without sample preparation or process interruption.

Future Trends and Opportunities

Advancements in process analytics point toward tighter integration with Industry 4.0 frameworks. Future developments may include enhanced machine learning models for predictive process control, digital twin simulations driven by real-time NIR data, and further miniaturization of sensor heads for decentralized monitoring. Expanded connectivity via IoT interfaces will support comprehensive condition monitoring and remote diagnostics.

Conclusion

The MATRIX-F II FT-NIR spectrometer represents a versatile, reliable solution for inline process analysis. Its combination of high-speed NIR measurement, modular sampling options and robust software connectivity supports a wide range of industrial applications, driving efficiency gains, product quality improvements and operational cost savings.
