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.
