Digital Image Spectroscopy an Innovative Approach for Particle and Bulk Powder Characterization

The need to develop and utilize more and more affordable, easy to implement and utilize, as well as characterize, by low costs and highly reliable analytical tools able to produce affordable and robust procedures finalized to perform an optimal particles and particles systems physical-chemical characterization, referred to specific products, represents one of the most important topic of the sector.

The role played by innovative particles technology approaches, both at the “preliminary stage” of their characterization (i.e. laboratory scale), and to the further “correct handling” and processing (i.e. plant scale), is thus becoming more and more relevant. The fulfilment of this goal assumes a dramatic importance when the selected technologies have to be designed, set up and implemented, in a cost-effective perspective, and assuring at the same time enough accuracy to create high-quality products and/or to perform, at the same time, correct investigations.

In this work, some of the hyperspectral imaging (HSI) based applications, originally developed by the authors with particular reference to particulate solids materials/products of different origins, characteristics and resulting processing actions, are presented, discussed and critically evaluated
