COMPREHENSIVE KARL FISCHER
TRAINING COURSE
Karl Fischer is a well-established routine technique for accurate determination of water content in samples. However, the accuracy of results, reliability and robustness of this technique are dependent on many factors. Many laboratories struggle to achieve consistent results or find the technique time-consuming, frustrating and resource intensive.
As with any analytical technique, when we look in detail at how we apply this in day-to-day laboratory practice, there is a lot more to this technique than we might expect. Getting the best from Karl Fischer does rely on understanding how it works.
Our training looks comprehensively at Karl Fischer titrations, but with the focus always on getting the best from the technique in everyday analysis. We look in detail at the areas of the equipment and analyst technique that will significantly improve the efficiency of your practical analysis and quality of your results. Your team will have less downtime, less repeat analyses, and generate fewer errors.
The material is supported by embedded workshops that consolidate learning, improve understanding, and allow delegates to formulate solutions to real-world problems that are used as the basis for the troubleshooting material.
