Tips and tricks for Karl Fischer water determination using the oven method

Karl Fischer (KF) titration is an industry standard method for measuring water content in all types of substances. However, for various reasons some substances are not suitable for a direct Karl Fischer titration:

• They release their water only slowly
• The water is released at high temperature only
• The substances are poorly soluble in KF solvents
• undergo side reactions with KF reagents
• They contaminate the titration cell or the electrodes

By using the KF oven method, the above-mentioned problems can be avoided. This makes the KF oven method a perfect solution for the analysis of difficult samples.

By viewing this webinar you will learn…

• how to handle liquid samples and water standards correctly
• how to analyze difficult samples
• how to properly prepare your titration system with the KF oven
• how to prepare your sample
• how to select the optimal heating temperature
• which reagents and which water standards you should use to obtain accurate results

After viewing this webinar you will know how to perform accurate titrations using the Karl Fischer oven method. Additionally, the speakers will reveal tips and tricks to help you in the daily routine. The webinar will finish with a live Q&A session.

This webinar will be moderated by Allison Reiter, Offering Management Lead – Honeywell Research Chemicals.
