In this study an objective and neutral olfactive evaluation through an electronic nose has been performed on recycled PET samples. The differences respect to a reference have been clearly identified, allowing to improve the recycling processes and accelerate product development.
Several pharmaceutical ingredients (API) tend to crystallize in different crystalline packings (polymorphs). In a pharmaceutical formulation, the identity or the possible conversion of the API polymorph could alter the characteristics and the efficacy of the pharmaceutical form, leading to a different bioavailability. In this work we show how polymorphism can be successfully recognized and characterized by using MDRS (Morphologically-Directed Raman Spectroscopy), a powerful technique that combines automated particle imaging with Raman spectroscopy to provide particle size, shape and chemical identification in a single analysis.
A good understanding of powders behaviour allows you to optimize productivity and improve product quality. Freeman Technology's FT4 powder rheometer is the best technique to understand and resolve powder flow issues.
