Multispectral fiber sensing for remote process control
– to compare key spectroscopy methods for a smart selection of the best way of remote reaction monitoring in real time under harsh environment and to develop spectral fiber sensors customized for dedicated process control

31/08/17 at 3pm (UK time)

Remote control of chemical changes during reactions enables to run process-control for enhanced yield, improved product quality, for a time and cost savings. Fiber coupled spectrometers provide the best way to do process-control in-line – as they eliminate the need of sampling and tests in sample chambers, while fiber probes can do it at distance from a few to hundreds of meters and can withstand to the harsh process parameters: toxic or aggressive chemicals, vibrations and high pressure, high or low temperature, under radioactive or high tension fields.

The most informative and accurate method of process-control must be chosen from the variety of key spectroscopy methods used for chemical analysis of media composition: spectra of its absorption/ transmission, reflection, fluorescence or Raman scattering, -as they possess by their specific advantages and drawbacks to be compared. Description of Multi-Spectral Fibers MSF-System will be presented in this webinar - which includes all 4 types of spectrometers with fiber probes for the test of any media or reaction in parallel. Comparison of results obtained by all key methods enables to select the best one for sensitivity, specificity and accuracy. If there is no chance to select one method due to its outstanding advantages – then the best 2 or 3 methods can be united in one combi-fiber probe to achieve the synergy fusion of the obtained spectral data.

This webinar will describe experimental MSF-system including 4 spectrometers with fiber probes made for one method or 2-3 methods combination – for a broad spectral range span from 300nm to 16µm, including the ‘‘finger-print’’ part of Mid IR-spectrum covered by FTIR-spectrometers with ATR- and Trans-Flex probes. Several promising applications will be presented to demo 2 unique possibilities:
1) to use MSF-System for a fast selection of the best spectral method (or methods combination) derived from experimental tests for any reaction / process control;
2) to derive spectral fiber sensors design from MSF-system trials for dedicated process control. These sensors will gain low cost and small size as they use only information rich spectral features instead of broad spectra with high resolution. Design of customized SF-sensors will match IoT concept - with friendly software, data transfer to iCloud and compatibility with automated production in plants.
