Coulometer including generator electrode without diaphragm and complete volumetric titration cell. The coulometric Karl Fischer Titration is the method of choice for low level water determinations (10 μg … 10 mg absolute water content) in liquid, solid and gaseous samples. As it is an absolute method a titer determination is not necessary. With the 852 Titrando coulometric as well as volumetric Karl Fischer titrations are carried out straightforwardly and quickly.
