Why Choose Karl Fischer Titration? Principles and Scientific Advantages

KF titration is based on the quantitative reaction of iodine with water in the presence of sulfur dioxide and a basic medium. It can be performed using either volumetric or coulometric methods and offers the following scientific advantages:

• High sensitivity: Capable of detecting trace moisture down to the ppm level;
• High selectivity: Highly specific to water with minimal interference from other components;
• Wide applicability: Suitable for liquids, solids, and gases;
• Flexible testing setups: Compatible with high-temperature pyrolysis systems and inert atmosphere configurations for handling complex or hygroscopic samples.

These characteristics make Karl Fischer titration the preferred method for high-standard moisture determination in research laboratories.
