Alfatestlab provides scanning electron microscopy (SEM) images including elemental analysis EDX (Energy Dispersive X-ray Analysis) when required. SEM images and EDX analysis provide fundamental information with a resolution down to 10nm. Thanks to a dedicated software, Alfatestlab can provide additional data using embeded image analysis algorithms dedicated to various applications: fiber analysis (membranes, filters), size and shape analysis of particles, size and shape of pores, analysis on frozen samples (biological samples and in general liquids), imaging of three-dimensional objects, failure analysis etc. Ask us about your application!
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.
