Short description about presentation:

FTIR spectroscopy is a well-established quantitative analysis technique, but it's application to harsh production processes typically found in petrochemical plants has to date been restricted by the inherent fragility of Michelson interferometers and fibre probes. Keit's IRmadillo FTIR has no moving parts, and so overcomes these obstacles allowing the measurement of concentrations of multiple species of interest simultaneously over a wide range of concentrations simultaneously. Here we present the methods and methodology of calibrating the same spectrometer to work in a number of different processes of interest to the petrochemical and bulk chemical industries. We will present the results for calibration of the spectrometer to monitor BTEX levels in water, total acid number, alcohols in gasoline, water in glycol levels and water in common solvents. Attention will be paid to ensuring concentration prediction models are robust, long lasting and even transferable from instrument to instrument.
