What is coulometric Karl Fischer titration? Coulometric titration is used to determine trace-levels of water in samples within a range of 10 µg to 200 mg water. However, larger amount of water (> 10 mg) require a lot of time and/or may exceed the water capacity of the KF reagent, which could lead to incorrect results.It's always good to know before you buy! Please see our Product Disclaimer for more information.. For scientists and professionals who need exact water content determination from 1 ppm to 5%, our new generation of the Coulometric Karl Fischer Titrator is engineered to meet or exceed your technical requirements while delivering a lower cost of ownership.
It involves titrating the sample with a Karl Fischer reagent, which contains iodine, sulfur dioxide, and an alcohol solvent. There are two main types of Karl Fischer titration: coulometric titration, where iodine is generated in the titration cell, and volumetric titration, where a solution with a known iodine concentration is used as the titrant.Coulometric Karl Fischer Titrator TQ-3000; Volumetric Karl Fischer Titrator TQV-3000; Titration Station Drive TS-3000; Stirrer K-3000T (for titration) SOLID EVAPORATOR EV-2000; OIL EVAPORATOR EV-2000L; AUTOMATED SOLID EVAPORATOR EV-2010; AUTOMATED SOLID EVAPORATOR SE-320; AUTOMATED OIL EVAPORATOR LE-320
