The sample is weighed into its own sample vial and hermetically sealed, which minimizes contamination and carry over effects. Using PTFE-covered septa prevents any moisture uptake from ambient air. The vial is placed in the oven chamber and heated, a carrier gas transfers the released water to the titration cell, where it is then determined by KF titration. Depending on the sample’s water content, the subsequent KF water determination can be carried out volumetrically or, for trace amounts, coulometrically. Since only the water enters the KF cell and the sample itself does not come into contact with the KF reagent, unwanted side reactions and matrix effects are eliminated. You can determine the water content of solids (powders or granules), liquids of different viscosities, plus pastes and fats.
