ReactIR Continuous Flow Analyzer

FTIR Analyzer for Continuous Flow Chemistry Applications

Researchers are increasingly using continuous flow chemistry to develop new reactions and processes with increased specificity, yield and product quality. Optimization of this work is often challenging as offline analytical techniques, such as High-Performance Liquid Chromatography (HPLC), cannot provide fast enough informa­tion to optimize the reaction in real time. A dedicated ReactIR Fourier Transform Infrared Spectroscopy (FTIR) instrument for in-situ, real-time monitoring of continuous flow chemistry, enables researchers to save valuable time and materials when screening and optimizing their reactions.

Examples of ReactIR value in continuous flow chemistry include:

  • Oxazole formation
  • Fluorination reaction
  • Accurate control of reagent addition in multi-step segmented flow processes
  • Analysis of a continuous process for alkene ozonolysis
