Extracting all water content, maintaining a pH range between 5 and 7, and avoiding side reactions in the solvent system are critical to the accurate determination of water content in samples.

This webinar will focus on how the system can be modified to fit the needs of the sample. To improve solubility, the addition of a co-solvent, the elevation of the system’s temperature and the addition of a homogenizer are all acceptable methods of improving water extraction from the sample. The addition of an appropriate buffer may be required to maintain proper pH control. Problematic functional groups and the specialty reagents that allow for their analysis will be discussed. In addition, the Karl Fischer Oven will be discussed with regard to insoluble or problematic samples.

A brief overview of different standards and how they may be used to verify that the system you are working on is functioning properly, will be covered as well.

During this webinar you will:

  • Understand the importance of choosing the correct KF technique and reagents for different sample types
  • Learn how to optimize KF titration for specific sample types
  • Learn how to use standards to verify sample results
