Many substances release water slowly or only at high temperature, which is not suitable for direct Karl Fischer titration;

There are also some substances whose solubility in alcohol solutions is very low. In this case, traditional methods usually recommend complicated sample preparation processes or the use of health-damaging co-solvents;

In addition, especially in some pharmaceutical factories and material production plants, there is still the problem of mutual contamination between samples. There are often interfering substances in the samples that affect the normal progress of the Karl Fischer reaction, and side reactions with KF reagents release water or consume iodine, leading to erroneous results.

The 885 automatic headspace heating cassette moisture determination system can solve the above-mentioned problems and is specially suitable for the moisture determination of these difficult samples.
