Tips and tricks to analyze difficult samples using the Karl Fischer oven technique

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

• They undergo side reactions with KF reagents

• They contaminate the titration cell or the electrodes

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

By viewing this webinar you will learn…

• how to analyse difficult samples

• how to properly prepare your titration system with 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 technique. Additionally, the speakers will reveal tips and tricks to help you in the daily routine. The webinar will finish with live Q&A session.
