HYDRANAL VOLUMETRIC TWO-COMPONENT TITRATION
Two-component reagents have been developed to use the stability advantage of a pure alcoholic solution of iodine. Additionally, the buffered system provides a very fast titration performance.
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.
Further types of Solvent reagent based on different mixtures enable to meet the sample dissolution properties.
Advantages of two-component reagents include:
• High titration speed Titrant
• Ideal accuracy for small amounts of water
• High buffer capacity
• Exact and stable titer
• E-type and FI-type reagents: reduced toxicity compared to methanol and/or imidazole
• Long shelf life (three years for titrants, five years for solvents)
