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. . There are two methods used to perform Karl Fischer testing, volumetric and coulometric. . Particle Size Distribution Analysis; Particle Size Distribution Analysis Laboratory;Karl Fischer (KF) titration is a widely accepted method for determining the water content in a sample, with volumetric Karl Fischer titration being the most used technique, measuring water content from 100 ppm to 100%. However, achieving accurate results can be challenging, as several factors can influence the outcome.
Volumetric KF Titrator V10S/V20S/V30S User Manual 30297193C 7/18/2017 12:15 PM - Schema ST4 PDF engine - Layout by Victor Mahler Volumetric KF Titrator. Table of Contents 1 Introduction 3 . operate instrument for volumetric Karl Fischer titrations. About this documentThe different ways of producing iodine can be divided into the coulometric method and the volumetric method. Karl Fischer Titration Principle. The KF reaction is based on an earlier reaction called the Bunsen reaction, in which sulfur dioxide is oxidized by iodine and consumes water in the oxidation process. The initial response is as follows:• Titrator with a mode for volumetric Karl Fischer titration • Analytical balance (minimum resolution 0.1 mg) Accessories • Plastic or glass syringe and 6needle with a thickness of approx. 0.8 mm (for liquid standards) • Glass weighing spoon (for solid standards)directly in the titration cell. Instead, in volumetric KF titrators, a burette injects the titrant into the titration cell. Coulometric titrators measures water contents that are much lower than the volumetric titrators (Section 3.2).[6] 3.1 | Volumetric KF The volumetric KF instrument consists of a titration vessel
