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!
The synthetic and natural HA differ in terms of physical microstructure, crystal size, and porosity, but chemical similarities to bone, in both forms, as well as biocompatibility, bioactivity and thermal stability in the body fluid pose Hydroxyapatite (HAp) as an attractive material for a wide range of applications in the biomedical field.

Silica is one of the most complex and most abundant families of materials: sand, quartz, silica gels, precipitated silica, fumed silica, colloidal silica, mesoporous silica nanoparticles (MSNPs)... Any type of silica material finds specific applications and needs specific physical characterization!
There is a direct correlation between the physical properties of the powder on the one hand and the performance of the process and the properties of the final components on the other. Therefore, characterisation of the powders allows for process optimisation and improves the finished product.
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.
