Particle size distribution analysis is one of the services offered by Alfatestlab for the characterisation of powder, suspension and emulsion products. Accurate particle size distribution over a representative number of particles is a key quality parameter for a variety of products in many industries.
Alfatestlab is equipped with the latest technology platform to provide rapid, reliable and accurate characterization of EVs and exosomes following MISEV 2018 guidelines1. Based on NTA and Exoview analysis, our services for EVs and exosomes offers multidimensional data sets enabling an advanced understanding of complex EV populations.
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.
Alfatestlab provides real density analysis of solids, powders and slurries using helium picnometry. Density is an important physical characteristic of materials. It is defined as the relationship between the mass of an object and its volume. Density indicates the amount of a material that occupies a defined volume at a certain temperature.
Alfatestlab provides BET specific surface area, as well as pores dimensional distribution and volume analysis of solids and powders with gas physisorption techniques. Surface area and porosity are physical properties that influence the quality and behaviour of porous materials: materials with identical weight and volume but different specific surface area may differ in terms of surface activity and adsorption volume.
Material characterization throught thermal analysis techniques: DSC (Differential Scanning Calorimetry) and STA (simultaneous thermal analysis, also known as TG-DTA or TG-DSC) instruments are available to perform studies upon a wide variety of materials.
