Volumetric Karl Fischer Titration

Advantages of Hydranal one-component reagents:

New formulation of Hydranal-Composite reagents improves stability and eliminates the formation of crystals
Hydranal-Methanol Rapid contains accelerators to speed up titration
Hydranal-Medium K suitable for methanol-reacting compounds, e.g. ketones and aldehydes
Unlimited water capacity
Convenient and easy to use
The greatest flexibility in working media selections
Long shelf life (3 years)

Improved Composition

Hydranal-Composite contains all the reactants, including iodine, sulfur dioxide, and the bases imidazole and 2-methylimidazole, dissolved in diethylene glycol monoethyl ether (DEGEE). Adding 2-methylimidazole in addition to imidazole improves stability and eliminates the formation of crystals which can interfere with the titrator’s performance.

Volumetric Karl Fischer Titration

Advantages of Hydranal two-component reagents:

High titration speed
Ideal accuracy for small amounts of water
High buffer capacity
Exact and stable titre
E-type reagents based on ethanol for safer titrations
Long shelf life (3 years for titrants, 5 years for solvents)

Composition

In two-component reagents, the Karl Fischer reactants are separated into two solutions: the titrant and the solvent. Hydranal-Titrant contains iodine dissolved in an alcohol with a precisely defined concentration. Hydranal-Solvent is an alcoholic solution of sulfur dioxide and imidazole.

The alcohol is either methanol for standard reagents or ethanol for E-type reagents.

Coulometric Karl Fischer Titration

Coulometric reagents based on different solvent compositions serve to support the broad variety of samples analyzed. Some working techniques are supported by special reagents:

Karl Fischer ovens by Coulomat AG-Oven
Cells without diaphragm by Coulomat AD

Advantages of Hydranal coulometric reagents:

Easy to use
High accuracy for trace amounts of water
Stable conditions of the titration vessel
Broad product range
Long shelf life (up to 5 years)

Hydranal-Coulomat A-type or E-type reagents are used as anolytes. The anolytes contain iodide and a sulfur dioxide/imidazole buffer in suitable solvents.

Hydranal-Coulomat CG reagents are used as catholytes.
