analysis and explanation

The concentration (efficiency) of Karl Fischer titration agent decreases over time. Therefore, potency, as a correction factor to counteract this effect as well as changes in equipment, personal operations, and laboratory conditions, must be measured immediately after opening a new bottle and should be verified regularly.

Coulomb method: applicable to samples with moisture content<1%

Brand: GermanyMERCK
Origin: Germany
Usage: Both diaphragm reaction tanks and non diaphragm reaction tanks are available

Advantages:

1The anode and cathode only need to1Bottle reagents;

2Very high precision and reproducibility;

3The equilibrium time of the reaction tank is short;

4Does not contain chlorinated hydrocarbons.

Karl Fischer titration method19century30Since its discovery, due to its wide range of moisture detection, it can be applied to various material samples such as food, chemicals, pharmaceuticals, cosmetics, and mineral oils, and has therefore been widely used worldwide. The Karl Fischer titration method is based on a chemical reaction with water to detect water content, and can accurately determine water.

At present, the Karl Fischer titration method has been included in the pharmacopoeias of various countriesSOPs(Standard Operating Procedure)ISO9000ffTheASTM(American Society for Testing and Materials) andDINListed as a standard guidance method by the German Institute for Standardization. The Karl Fischer titration method is fast, accurate, and stable, and is not affected by sample type, aggregation state, or the presence of volatile substances.
