We are a leading supplier to the global Life Science industry with solutions and services for research . You need a fully equipped titrator for volumetric KF titration, as well as the KF reagents (titrant and solvent).. Another prerequisite for accurate titer determinations is an analytical balance with a minimal resolution of 0.1 mg.. Last but not least, you need a standard containing a known amount of water and some tools to add the standard to the titration vessel. This blog article explains the most important factors to consider in order to choose the optimal Karl Fischer titration technique: coulometry or volumetry. Coulometric Karl Fischer titration (KFC) is generally used for samples with a low moisture content between 0.001% to 1%. Volumetric Karl Fischer titration (KFT) is used for samples with higher levels of moisture .
If you want to learn about water content determination, volumetric Karl Fischer titration is a reliable and accurate method used in the pharmaceutical industry. The US Pharmacopeia and European Pharmacopoeia have established guidelines and regulations for using this method to ensure consistent results.Titration cell of a standard volumetric Karl Fischer (KF) automatic titrator. The burette injects the KF reagent and this pre-treats the solvent; the sample port allows the addition of the sample with the same procedure. A double platinum electrode measures the controlled-current potentiometry to establish the endpoint.The Karl Fischer method determines only water and no other compounds because of the selective and stoichiometric reaction between the water in the sample and the iodine in the reagent. There are multiple different ways to release the water from the samples and determine the correct water content. . For a volumetric titration, a higher amount .Customizable Methods.
