Simple solution for difficult samples


The oven method allows you to analyze samples that cannot be titrated directly, e.g., because your sample:

  • does not dissolve easily,
  • releases the water only at elevated temperatures, or
  • reacts 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

Cost-effective and easy: Save time and money

Automating sample preparation means eliminating manual work and thus saving time. In addition, by automating sample preparation, you can increase the accuracy of your determinations, as each sample is handled in exactly the same way.
