NIR spectroscopy coupled with fiber optic probes provides an ideal online measurement solution for both water and acetaldehyde in acrolein in real-time. For 1 or 2 sample points a Guided Wave ClearView db filter photometer can provide the measurement of low percentage levels of water and acetaldehyde in the final product. NIR methods minimize the need for laboratory sample collection. Results are available in real-time (seconds). Acrolein is highly toxic, with online analysis using Guided Wave’s ClearView db analyzer, manual sampling is avoided thus providing the safest and most efficient control of the Acrolein process. For more detailed information regarding system selection or specifications please contact a Guided Wave sales or technical specialist.
Why Use Process Spectrscopy?
The NIR region of the electromagnetic spectrum allows the use of the overtone and combination bands of the C-H, O-H, and N-H fundamentals. By measuring the NIR absorbance data for a series of acrolein samples of known water concentration, a quantitative model can be developed which will allow the measurement of future samples based only on their NIR absorbances. Guided Wave analyzer systems use fiber optics to allow the sample probe to be located in remote locations away from the spectrometer itself.
