karl fischer volumetric vs coulometric
Karl Fischer (KF) published his manuscript “New procedure for the determination of the water content in liquids and solids.” (K. Fischer; Angew. Chemie 1935, 48, 394). Karl Fischer titration, as it was to be known, could be followed by nearly any laboratory interested in water determination. Consequently, it has become one of the most .MM: We recommend carrying out a volumetric or coulometric Karl Fischer titration using a certified standard as a sample. In volumetry, a threefold titer determination followed by a determination of a different standard is carried out and the recovery of the water content in the determination of the standard is calculated.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 containsThe AQV-2200A Karl Fischer Volumetric high-end titrator is the perfect choice for a very wide range from 10ppm to 100% water content with its maximum capability for automation and future upgradability.
