The RDI service dedicated to the assessment of water and moisture content in liquid and solid samples offers precise analytical support for evaluating the stability of materials and optimising processes. Karl Fischer coulometric titration is used to determine trace moisture levels in samples that require high analytical precision, including oils, fuels, solvents, polymers, pharmaceutical products, chemical substances and other liquid or solid materials.
The results obtained provide essential information on product quality, storage conditions, material stability and critical technological parameters. The precise control of water content is important for preventing degradation, undesirable secondary reactions, loss of performance and non-conformity with technical standards. For samples with a higher moisture content, thermobalance analysis can be applied, allowing moisture to be determined through controlled heating and the continuous measurement of mass.
The service supports improved shelf life, safety assessment, compliance with regulatory requirements, raw material qualification, process control and the optimisation of manufacturing conditions. It is relevant to the pharmaceutical, biotechnology, life sciences, food, animal feed, agricultural, energy, electrical, petrochemical, petroleum, chemical, polymer, plastic materials and advanced materials industries, as well as to industrial research and development units and testing laboratories.
Delivering the service requires specialised equipment and resources, including a Karl Fischer coulometric titrator, an analytical balance, a halogen moisture analyser, specific reagents and solvents, sample preparation accessories adapted to the type of sample and certified reference materials for method verification and for ensuring analytical reliability.
