FTIR Process Analyzer for Real-Time Industrial Process Monitoring

ABB’s FTIR Process Analyzer portfolio combines the power of FT-IR and FT-NIR spectroscopy to provide real-time, multi-point process monitoring in harsh industrial environments. For full product specifications, refer to the ABB process spectrometers page. These analyzers are trusted across chemical, pharmaceutical, petrochemical, and semiconductor industries for their accuracy, reliability, and adaptability.

Advanced Spectroscopy for Continuous Process Measurement

The TALYS and FTPA2000 series support direct integration into process lines or reactors, providing continuous measurement of gas, liquid, slurry, or solid streams. Systems like the TALYS ASP500 and ASP400 offer compact, robust enclosures suitable for hazardous areas, while the FTPA2000 series provides flexible sampling options, fiber-optic coupling, and multi-channel analysis capabilities.

For laboratory-based method development and calibration, the FTIR Laboratory Analyzer provides a complementary platform for transferring analytical methods from lab to process.

Designed for Demanding Industrial Applications

FTIR Process Analyzers are engineered for applications such as crystallization, hydrogenation, polymerization, fermentation, and solvent drying. These systems enable optimized reaction control, reduced batch cycle times, and improved product consistency.

ABB’s Horizon software ensures intuitive control, spectral acquisition, and seamless integration into existing process control systems. With minimal calibration drift and long-term stability, these analyzers reduce maintenance requirements while improving measurement confidence.

Flexible Installation and Hazardous Area Capability

Each system is designed for reliable real-time operation with rapid data output, enabling immediate corrective action during process changes. Robust enclosures and fiber-optic remote sampling options allow installation in Class I Division 1, ATEX, and cleanroom environments without compromising safety or performance.

This flexibility supports both batch and continuous processes, making FTIR Process Analyzers ideal for applications requiring stable, in-line measurements across single or multiple measurement points.

Proven Performance Across Critical Processes

With over 30 years of deployment in field installations, ABB’s FTIR Process Analyzer platforms provide validated performance for applications such as API production, catalyst optimization, polyol QA/QC, and solvent recovery. Users benefit from reduced reliance on laboratory analysis, enhanced automation, and simplified process validation workflows.

For ultra-trace gas analysis where sub-ppb detection is required, complementary technologies such as CRDS Gas Analyzer systems can be integrated alongside FTIR to provide a complete analytical solution.

Real-Time Insight for Process Optimization

These analyzers reduce operating costs while enabling faster product release through real-time decision-making. Their adaptability and precision make them a critical component of modern digital process strategies.

By integrating an FTIR Process Analyzer into your control loop, operators gain reliable insight to maximize process safety, regulatory compliance, and overall productivity across industrial operations.
