Summary on Grant Application Form |
|
Product quality specifications of particulate systems such as emulsions and slurries, are based both on chemical and physical characteristics viz. composition, particle size, shape, size distribution, surface charge etc. Therefore in the chemical processing of such systems, continuous monitoring of these parameters is required to ensure optimal operat to maximize yield and reduce variability in quality by providing the ability to detect deviations from target quality and to timely corrective actions. This will lead to enormous savings by reducing incidences where products fail to meet quality specifications or targeted yields. While in principle, measurements using several instruments can be made to obtain th physical and chemical characteristics of particulate systems, it is obvious, considering cost and logistics of online implementation, a single instrument that can fully characterize a suspension is highly desirable and practical. Spectroscopic measurements using the visible-near IR region of light contain information on both concentration and particle characteristics, and components for small, cheap and robust spectrometers for this wavelength range are easi available. Therefore the proposed research aims at establishing a multi-faceted research programme to develop techniques for the complete online characterization of particulate systems using vis-NIR spectroscopy measurements. This will be achieved by integrating measurement strategies, fundamental light propagation models (that describe the scattering and absorption effects of the particulate system on the incident light ) and multivariate statistical modelling techniques. The research will focus on the challenge of separating the scattering and absorption effects and then extracting the pertinent physical and chemical information using visible-NIR spectroscopy measurements.
