Determination of Water Content in Bio-Oils by Volumetric Karl Fischer Titration . Laboratory Analytical Procedure (LAP) Issue Date: October 7, 2021 . Joel Miscall, Earl D. Christensen, Steve Deutch, Rebecca Jackson, and Jack R. Ferrell III . National Renewable Energy LaboratoryKarl Fischer Titration is a technique for the determination of moisture content. The technique was developed by a chemist named Karl Fischer. It is based on a reagent which reacts with water and converts the water into a non-conductive chemical. The Karl Fischer (KF) titration is a method of determining the water content of solid, liquid and gaseous samples. It is the technique preferred for use in industrial quality control. In principle it involves the oxidation of sulfur dioxide by iodine, in the presence of water, in a buffered solution.VOLUMETRIC KARL FISCHER TITRATION Volumetric determination of water can be done with one-component or two-component titration. In one-component titration, all of the reactants needed for the reaction are present in a single solution. Two-component titration uses two solutions - one of them is a solvent that contains

The Karl Fischer (KF) titration is a method of determining the water content of solid, liquid and gaseous samples. It is the technique preferred for use in industrial quality control. In principle it involves the oxidation of sulfur dioxide by iodine, in the presence of water, in a buffered solution.The Karl Fischer (KF) Titrator is exclusively used for the quantification of water. In a volumetric KF titration, the iodine solution, also known as the “titer”, will react with a sample that contains water in a methanolic solution until all the water is consumed. Before proceeding with a sample measurement, ensure the Titer concentration hasWater Determination by Karl Fischer Karl Fischer titration has become one of the most widely used techniques for the determination of water content in a variety of substances. Many pharmaceutical products contain water in adsorbed form, and as a result, the de-termination of the water content is important in demon-
