Jonathon Speed, PhD, of Keit Spectrometers presents the calibration and use of a static optics FTIR spectrometer specifically targeted at seed oil refining. Speed provides a brief overview of the main types of spectrometer, their strengths and weaknesses and use cases. He also explains the calibration process for a spectrometer, and discuss the merits of different calibration use cases – namely partial least squares (PLS) for real-time concentration monitoring or principal component analysis (PCA) for more qualitative measurements.
This presentation also shows the performance of monitoring total free fatty acids and fatty acid methyl acids in real time, as well as the ability to discriminate between the chemicals to better understand the makeup of the feedstock seed. Speed also explores the other sorts of chemicals that can be measured using this approach (such as phosphorus, water, soap and glycerol). Lastly, this presentation shares the results on an online trial at a manufacturing facility to investigate the chemicals of interest during production in real world samples.
