Our premium Hydranal™ products for pyridine-free and ethanol-based water determination by Karl Fischer titration (KF titration) is comprised of one- and two-component reagents for volumetric and reagents for coulometric Karl Fischer titrations.
Also available are water standards for titer standardization, pH buffering reagents, special reagents for aldehydes, ketones, and other solubilizing agents.
Explore the many benefits of the broadest portfolio of one- and two-component volumetric reagents.
New formulation of Hydranal-Composite reagents improves stability and eliminates the formation of crystals.
Our broad selection includes:
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 as a less toxic alternative for the determination of water in aldehydes and ketones
Optimize your titration with the right reagents
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)
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.
The complete KF Titration solution from Honeywell
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)
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.
