Karl Fischer Micro Volumetric Moisture Analyzer

The Karl Fischer micro moisture analyzer is based on the Karl Fischer titration method, which measures the moisture content of a sample through the quantitative reaction of iodine with water. The instrument consists of a titration cell and electrodes. During detection, water in the sample undergoes an electrochemical reaction with the reagent, and the electrodes detect the endpoint to calculate the moisture value. It is used for quality control and moisture monitoring of materials such as coatings, inks, and plastics.
Selection
When selecting, consider matching the sample properties with the reagent type: use volumetric reagents for water-soluble samples and coulometric reagents for non-water-soluble samples. Determine the resolution based on detection accuracy requirements: choose 0.1% accuracy for routine needs and 0.01% for high precision. Select the titration cell capacity based on sample volume, typically opting for a 20 ml cell for routine applications. Pay attention to electrode compatibility and the instrument's protection rating.
