KF Titration: 5 Things You Could Be Missing

1. Other methods like loss on drying only measure surface moisture. Using Karl Fischer titration allows you to analyze the samples for total moisture content.

2. There are two main approaches depending on your sample's concentration. For low levels (think ppm), a coulometric approach is best. For higher concentrations of water, you should be using a volumetric technique.

3. The Karl Fischer reaction chemistry is the same for all samples. Making sure your sample doesn’t interfere with the reaction is key!

4. Not all samples give up their moisture easily. Some samples require extraction, homogenization or other sample preparation techniques to ensure all the moisture is titrated.

5 . Near infrared spectroscopy (or just, NIR) can be used to make quick moisture measurements without all the fuss of reagents.
