Moisture titrators are instruments designed to quantify moisture content within samples. They are commonly employed in industries such as food, pharmaceuticals, and environmental testing.
Moisture titrators utilize the Karl Fischer titration method. In this technique, a sample is dissolved in a solvent containing iodine and sulfur dioxide. The iodine reacts with water present in the sample, consuming it. The endpoint of the titration is reached when all water has been consumed, and the solution turns color due to excess iodine.
The volume of titrant used to reach the endpoint is directly proportional to the moisture content of the sample. This information can be used to calculate the moisture content accurately.
Moisture titrators find applications in numerous fields. They are commonly used for:
