The AQ-300 Karl Fischer Coulometric Titrator includes six built-in calculation modes for evaluating solid, liquid, and gas samples. The AQV-300 Karl Fischer Volumetric Titrator is an easy-to-use, more affordable system . I recommend carrying out a volumetric or coulometric Karl Fischer titration using a certified water standard as sample. In volumetry, you can carry out a threefold titer determination followed by a determination of a different standard. Then, you can calculate the recovery of the water content determination of the standard.
ric and volumetric. The main difference between the two techniques is how the titrant enters the system. In coulo-metric KF, an electrode generates the titrant in situ, 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
