Original and Innovative Karl Fischer Reagents

Looking to analyse or measure water content?

Hydranal™ products are the premium resource for pyridine-free and ethanol-based water determination by Karl Fischer titration (KF titration). They are comprised of one- and two-component reagents for volumetric KF titration, as well as reagents for coulometric KF titrations. Also available are water standards for titer standardization, pH buffering reagents, and special reagents for aldehydes, ketones, and other solubilizing agents.

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.
