Characterization of suspensions and emulsions by means of multiwavelength reflectance and machine learning methods AuthorS. Boldt, D. Lerche, P. Menesklou, O. Zhai, H. Nirschl Year2022 SourceFiltech Conference Abstract LanguageEnglish Pages1 2601LUMiFlectorLFlecMonitoring of product compositions is essential for the control of unit processes. Nowadays 4 more it is given a clear preference to in-line solutions. Product quality parameters have to be observed in almost real-time and the sensor should be used for different applications. This contribution introduces the Multi-Reflectance-Spectroscopy (MRS) as an innovative technique based on multiwavelength reflectometry for in-situ quality/process control of suspensions and emulsions. This technology is fasthas no direct contact to the sample and is applicable without any chemicals and sampling. Using machine learning approachesthe measuring signals can be correlated with quality parameters of dispersions (e.g.suspended solid concentration or particle size) with high accuracy. We present exemplary the potential of machine learning methods improving prediction-accuracy in process industry and give various example applications and results of suspensions and emulsions More details EditionL14 - Metrological Analysis of Data for Particle/Liquid-Separation LocationKöln, Germany, 8.3.-10.3.2022 Internal reference2601 Open publication →

It facilitates the subsequent production of nanoparticles loaded with the phenolics (Np-TPC) by ionic gelation. Howeverneither the effects of Ch concentration on encapsulation efficiency (EE%) of TPC nor which compounds are extracted in its media are knownbeing it the first objective of this study. The second objective was to analyze the stability of the Np-TPC under accelerated conditions and its release profile at pHs 3.0 and 7.0.
