Karl Fischer

Karl Fischer (KF) Titration is a technique for the determination of moisture content. It is a process based on the reaction of iodine with water. The KF method is one of the few techniques that will measure water content and not be affected by other volatiles. Alera labs are capable of performing coulometric titration. For coulometric titration the reagent and solvent are combined in the titration cell. When a sample is introduced into the titration cell and dissolved, reagent is released by the induction of an electrical current. The moisture is determined by the amount of current required to consume the water. The advantage of the coulometric KF method is the capability to accurately measure small amounts of moisture.
