Product Description

GD-2122C Fully Automatic Coulometric Karl-Fischer Titrator Micro Moisture Tester

 

What Is coulometric Karl Fischer Titration?
The coulometric Karl Fischer titrator is a powerful analytical tool used for the determination of water content in various types of samples. It is a highly accurate and precise method which offers quick and reliable results, making it a preferred choice for many laboratories.
The instrumentation of the coulometric Karl Fischer titrator is also straightforward and easy to use, with minimal training needed for operators. The instrument is also highly sensitive to water, making it an ideal choice for samples that have a low moisture content.
In addition, the coulometric Karl Fischer titrator is a very cost-effective method of analysis, as it requires minimal reagents and produces very little waste.
Overall, the coulometric Karl Fischer titrator is an important tool in various industries such as pharmaceuticals, food, and petrochemicals. Its fast and accurate analysis, easy-to-use instrumentation, low sample preparation requirements, and cost-effectiveness make it an important tool for many laboratories.

Operational principle:

Reaction of Karl Fischer Reagent and water is:
I₂+SO₂+3C₅H₅N+H₂O--2C₅H₅N·HI+C₅H₅N·SO₃   ...( 1 )
C₅H₅N·SO₃+CH₃OH--C₅H₅N·HSO₄CH₃            ...( 2 )
The reagent solution is mixed of iodine, pyridine, and methanol. Rest on the Faraday's law that the iodine which forms through the electrolysis on the anode has the direction proportion with electric charge quantity. The chemical formula is:
2I^--2e--I₂...(3)
From the formula 3, the iodine's molecule quantity equals to the water's. That's to see, according to the consumption of the iodine, we can know the water content of the test sample. The instrument adopts Faradic current automatic control system, can easily adjusts the Faradaic current, most to 200mA.
