Coulometric Karl Fischer
Coulometric Karl Fischer is a classical titration method in chemical analysis. It uses coulometric titration or volumetric titration to determine trace water in samples. It was invented by German chemist Karl Fisher in 1935. Today, the titration is done with Karl Fischer automatic titrator. Weshine® The developed Coulometric Karl Fischer (KF titrator) introduces the reliable performance, simple operation and space saving design of the compact KF coulometer. The accurate result is 1 ppm to 5% water. Each user can have up to 4 shortcuts + 5 analysis methods. With the Weshine® Coulometric Karl Fischer, the operator can conduct moisture measurement by pressing the button!

Product Description
Coulometric Karl Fischer
Coulometric Karl Fischer, also known as KF titrator, is used to determine the amount of water in the sample. Since the presence of water affects many characteristics of products, including reactivity, stability and quality, KF titration is very important in many industries and is used in many industries. The food, petroleum, pharmaceutical and semiconductor industries use Coulometric Karl Fischer to maintain product quality. There are two kinds of Coulometric Karl Fischer methods: volumetric method, which uses the amount of reagent to determine the amount of water; The coulometric method of electrolytic reaction uses electricity to tell us the amount of water in the sample. The volumetric method is suitable for the measurement of water from 1 to 100 mg, while the coulometric method is suitable for very small amounts of water from 10 micrograms to 10 mg. When selecting a suitable Coulometric Karl Fischer, several factors should be considered, including the size of the sample required, whether volumetric titration or coulometric titration is required, the time required for titration, the degree of automation in the process, and the amount of labor required.
