Physicochemical analyses in the laboratory: control the quality and conformity of your products

Physicochemical analyses cover a wide range of parameters to characterize a product from different perspectives, ensuring its conformity, stability, and quality throughout its life cycle. They are essential for controlling the formulation of raw materials, optimizing manufacturing processes, and ensuring compliance with current regulatory standards.

• General properties : measurement of pH, electrical conductivity, density, viscosity and refractive index, fundamental parameters for characterizing the nature of a product and anticipating 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 the conformity of food, cosmetic and pharmaceutical formulations to be verified.
• Purity control and identification : use of advanced techniques such as infrared spectroscopy (FTIR), ion chromatography, thermal analysis (DSC, TGA) or even DNA analysis (NGS) to guarantee the integrity and authenticity of products, by detecting possible contamination or falsification.
• Stability and aging : study of oxidation mechanisms, physicochemical variations under accelerated conditions of thermal or hygrometric stress, in order to predict the shelf life and the evolution of product properties over time.
• Interactions with the environment : evaluation of solubility, water activity, hygroscopy and other parameters influencing the conservation, bioavailability or even the reactivity of a product with its storage or application environment.
