The oven method offers a solution for the analysis of samples that cannot be titrated directly, e.g., because they:
- do not dissolve readily,
- release the water only at elevated temperatures, or
- react with the KF reagent.
In this method, the sample is heated and the evaporated water is transferred to the titration cell with a dry carrier gas. As a result, only the water gets in contact with the KF reagent, which means that the electrode and the titration cell are not contaminated. In addition, your results are more reliable, as carryover or memory effects are excluded.
