When accuracy, speed, and selectivity are needed for determining the amount of water in your product!
The Karl Fisher titration is the industry standard when quantifying the amount of water in a sample. This technique has the capacity to handle a wide range of water concentrations, whether your sample contains 100 ppm or 100% water.
This method involves combining the sample with the anode solution, composed of an alcohol, base, SO2 and I2. A second compartment contains a cathode immersed in the anode solution. Current driven into the Pt anode produced I2, which reacts stoichiometrically with water. Once I2 is formed in excess, a voltage drop between the Pt anode and a second Pt electrode signifies the end-point of the titration. Water concentrations can also be determined volumetrically by using the anode solution as the titrant.
- Quick and selective water determination
- High accuracy and precision
- Works with most sample types
