Description

Methanol-based solvent designed for volumetric two-component 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 titer
  • E-type reagents: reduced toxicity compared to methanol
  • Long shelf life (three years for titrants, five years for solvents)

Improved 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.
