Laboratory physicochemical analyses: control the quality and conformity of your products

Physicochemical analyses cover a wide range of parameters, allowing for the characterization of a product from various perspectives, ensuring its conformity, stability, and quality throughout its lifecycle. They are essential for controlling the formulation of raw materials, optimizing manufacturing processes, and ensuring compliance with applicable regulatory standards.

• General properties : measurement of pH, electrical conductivity, density, viscosity and refractive index, fundamental parameters to characterize the nature of a product and anticipate its behavior under different conditions of use.
• Elemental composition : analysis of water content (Karl Fischer method), ash, fat, protein (Kjeldahl and Dumas methods), glucosinolates and carbohydrates, allowing verification of the conformity of food, cosmetic and pharmaceutical formulations.
• Purity control and identification : use of advanced techniques such as infrared spectroscopy (FTIR), ion chromatography, thermal analysis (DSC, TGA) or DNA analysis (NGS) to guarantee the integrity and authenticity of products, by detecting possible contaminations or falsifications.
• Stability and aging : study of oxidation mechanisms, physico-chemical variations under accelerated conditions of thermal or hygrometric stress, in order to predict the shelf life and evolution of the product's properties over time.
• Interactions with the environment : evaluation of solubility, water activity, hygroscopy and other parameters influencing the preservation, bioavailability or reactivity of a product with its storage or application environment.
