The Chemical Laboratory of the Saint Petersburg Technopark provides residual moisture determination services using the Karl Fischer method. The method is based on precise quantitative measurement of water content in solid, liquid and semi-solid substances by titration involving iodine.
Analysis is performed on a modern volumetric titrator, ensuring high precision, reproducibility and sensitivity with minimal sample volumes. The method is suitable for assessing residual moisture in pharmaceutical substances, reagents, powders, lyophilized preparations and solutions.
Results can be used for quality control, stability confirmation and compliance with regulatory documentation.
