Automatic Karl Fischer Titrator Oil Moisture Analyzer

Automatic Karl Fischer Titrator Oil Moisture Analyzer

Introduction:

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. One of the major advantages of this titration technique is that it requires very little sample preparation. It can analyze samples with high moisture content as well as those with low moisture content, making it versatile for a range of applications.Overall, the coulometric Karl Fischer titrator is an important tool in various industries such as pharmaceuticals, food, and petrochemicals.

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.
