Effective Process Monitoring in Chemical Manufacturing

In-line chemical manufacturing

Improved Process Analytical Technology with FTIR

FTIR spectroscopy is a powerful tool for monitoring chemical reactions and is used heavily in chemical process development laboratories. The Keit IRmadillo™ FTIR spectrometer takes the power from the clean analysis lab and directly applies it even to the most challenging of outdoor (and indoor) production environments — subject many times to frequent vibration and variable operating conditions with exposure to environmental elements such as extreme cold or heat that standard FTIR laboratory instrumentation fail to operate in.

IRmadillo FTIR Applications and Capabilities in Chemical Manufacturing

  • Raw material testing
  • Product purity testing (e.g. measuring water in organic solvents)
  • Harsh environmental use (indoor or outdoor) over a wide range of ambient temperatures
  • Safe monitoring of potentially hazardous manufacturing processes (e.g. acetic acid production monitoring)
  • Endpoint measurement for better capacity utilisation
  • Blend uniformity
  • Detection of unwanted by-products or impurities (e.g. water in organic solvents)
  • Continuous crystalisation
  • Suitable for batch and flow systems

The ruggedness and reliability of the IRmadillo FTIR spectrometer enables direct in-line, real-time reaction monitoring, thus negating the problems traditionally associated with laboratory FTIR spectroscopy. Furthermore, as the instrument is immune to vibration. It is mounted directly on the reaction vessel for continuous and round-the-clock data readouts in the manufacturing of chemicals, and their intermediary products.

  • Fine, specialty, and basic chemicals
  • Petrochemicals
  • Agrochemicals
  • Plastics and polymers

Orange-TriAgrochemical Case Study

A major agrochemical provider stated they were experiencing up to 20% waste of production batches because they were unable to monitor reactions in real time with standard FTIR spectrometers that couldn’t handle the vibration or the ambient conditions of the outdoor production environment.


Keit provided a rugged FTIR spectrometer that could monitor the process at a key stage of the reaction. Positive study results included equivalent calibration models to existing bench-top FTIR and far greater long-term repeatability.
