You’ll learn the intricacies of cleaning, storage, and calibration procedures, safeguarding your electrodes from the risks of contamination and degradation.

Beyond electrode selection and care, optimizing titration parameters is paramount for achieving impeccable results. We will explore the intricacies of endpoint detection, titration modes, and other critical settings, enabling you to fine-tune your titration process for optimal accuracy.

By attending our comprehensive workshop, you’ll learn how to select the suitable electrode for your application, care, and titration optimization. Join us and elevate your titration skills to new heights of accuracy and reliability.

Afternoon Workshop: Useful Techniques for Accurate & Reliable Karl Fischer Water Analysis

Presenter: Eduardo Simoes, M. Sc.
Product Specialist, Titration
Metrohm, USA

Who Should Attend
Anyone performing Karl Fischer titrations will benefit from this workshop.

Abstract
Karl Fischer titration is a common laboratory measurement used for many sample types. Optimizing KF measurements is key to increasing lab productivity and maintaining product quality and process control.

For most materials, water determination is easy and straightforward. However, getting the right result quickly and reliably can be a challenge. Depending on the nature of the sample, some procedures are required for all the moisture in the sample to be measured. 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.

Some materials can cause side reactions with the standard reagents, overestimating the result. Choosing the right KF reagents is imperative to avoid any side reactions that may interfere with the water determination. For other materials, it may be necessary to use the Karl Fischer Oven to extract moisture from the samples and eliminate interferences.

Join this workshop and learn how to improve your water determination analysis. Attendees will leave with a better understanding of KF reagents, sample preparation techniques, and instrumentation for all sample types to get reliable and accurate moisture analysis.
