Volumetric KF Titration

Volumetric Karl Fischer Titration

Explore the many benefits of the broadest portfolio of one- and two-component volumetric reagents.

In addition to our broad selection of titrants with different concentrations, we also offer a selection of special solvents, including:

  • Hydranal-Methanol Rapid containing accelerators to speed up titration with one-component reagents
  • Hydranal E-Type reagents based on ethanol for safer titrations
  • Hydranal-Medium K for the determination of water in aldehydes and ketones

Advantages of Hydranal one-component reagents:

  • Unlimited water capacity
  • Convenient and easy to use
  • The greatest flexibility in working media selection
  • Suitable for methanol-reacting compounds, e.g. ketones and aldehydes
  • Long shelf life (three 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 the stability and eliminates the formation of crystals which can interfere with the titrator’s performance.

Advantages of Hydranal two-component reagents:

  • High titration speed
  • Ideal accuracy for small amounts of water
  • High buffer capacity
  • Exact and stable titer
  • E-type reagents: reduced toxicity compared to methanol
  • Long shelf life (three years for titrants, five years for solvents)

Composition

In two-component reagents the Karl Fisher 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.
