Abstract:

Multispectral fiber systems allow to run chemical reactions monitoring in-line – providing the synergy effect from combination of several methods of media analysis to track its composition changes in-situ. The latest design of innovative fiber optic probes coupled with different spectrometers enable to integrate several spectroscopic techniques within a single probe, providing simultaneous media analysis at the same point and time.

A strong advantage of fiber optic spectroscopy is in its capability to enable chemical process-control in-line in various applications, including harsh environments. Robust fiber probes can withstand temperature ranges from -150°C to +250°C, high pressure up to 200 Bar or in vacuum, and where there are vibrations, aggressive liquids or gases, or electromagnetic fields, including microwave and hard radiation. This advantage permits remote process-control to run even in industry – in contrast with soft laboratory conditions – and this feature is highly requested to secure sustainable process control. Depending on the chemical process or materials to be analyzed, fiber probes can be based on 4 different fiber types selected for the required spectral range and used for Transmission, Reflection, ATR-absorption, Raman & Fluorescence spectroscopies. Advanced fiber optic combi probes can unite 2-3 spectroscopy methods in the same probe, while spectral data fusion from them helps to enhance sensitivity and accuracy of the media composition analysis for automated process control in-line.
