Avoid common errors in volumetric Karl Fischer titration to improve the accuracy of your results. |
Karl Fischer (KF) titration is a widely accepted method for determining the water content in a sample, with volumetric Karl Fischer titration being the most used technique, measuring water content from 100 ppm to 100%. However, achieving accurate results can be challenging, as several factors can influence the outcome. As such, it is crucial to pay careful attention to specific details when performing the method to ensure reliable and precise titration results.
What are key considerations to ensure accurate results in volumetric Karl Fischer titration?
Accurate results in volumetric Karl Fischer titration rely on careful consideration throughout the entire process, from sample collection to the titration itself. Depending on the sample type, collecting, and introducing the sample to the titration cell can be challenging due to the sample matrix, and improper preparation and introduction can result in inaccuracies. Additionally, the accuracy of measurements can be impacted by inadequate equipment setup and selection of reagents.
