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 performs particle size analyses with laser diffraction technique in the 0.01 µm-3500 µm range and with dynamic image analysis in the 20 µm-3cm range. AlfatestLab offers other particle size analysis techniques such as static Automated Image Analysis (0.5-10,000 um), or SEM Scanning Electron Microscopy, we are available to perform the most suitable analysis for your application.

The MDRS technique allows dimensional analysis of a specific ingredient in a complex mixture, find out in the video how we proceed in Alfatestlab to characterize the API of nasal sprays !
The particle size of these ingredients influences the preparation of baked goods and can be critical in applications such as creams, icings, syrups, etc. where the presence of water induces swelling from particle hydration, which can alter palatability and more globally rheological properties. At Alfatestlab, we analyzed 6 powder ingredients for the QC department of one of our customers from food industry...
In Alfatestlab we support the food industry since several years in formulation, deformulation and bench-marking projects, trouble shooting and R&D by providing material characterization by innovative analytical techniques.
Size, shape and chemical identification of microplastic particles using Morphologically-Directed Raman Spectroscopy (MDRS®)
Let's meet at our booth 2C89!
In this study, we analysed food-grade calcium carbonates from different manufacturers, evaluating particle size and specific surface area.
Analysis of coffee particle characteristics, coffee creaming and bulk powder flow properties together with sensory analysis and high resolution SEM images can help you improve your coffee production process.
The unique potential of graphene, offering the theoretical strength of diamond together with the flexibility of plastic, finds application in a wide range of industries: from electronics to drug delivery. Graphene quality varies considerably depending on how the material is produced, so characterizing raw material and finished products is of fundamental importance.
Zinc oxide (ZnO) is an inorganic white powder, insoluble in water and used as an additive in numerous materials and products. Characterization of Zinc oxide powder and particles properties is fundamental to improve final product quality.
Chocolate is a complex suspension of non-fat particles (sugar, cocoa, milk powder particles) dispersed in cocoa butter. Particle size, rheology and thermal analysis help controlling texture, flavour and stability propeties of chocolate products. Discover how...

Physical properties of excipients influence the stability, bioavailability, and processability of the dosage forms. Alfatestlab is equipped with all the analytical techniques necessary to support you in choosing the right excipient for your formulation: particle size, particle shape, flowability, density, surface area and much more!
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.
Characterization of the API solid state is key to reduce possible future manufacturing or formulation issues and cut drug product development costs and time. Discover more!
Due to its high degree of microporosity, one gram of activated carbon can reach a surface area of 3,000 m2 as determined by gas adsorption. Discover more about its extraordinary properties!
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.
