HYDRANAL VOLUMETRIC ONE-COMPONENT TITRATION
Hydranal-Composite is the world‘s most frequently used pyridine-free Karl Fischer reagent.
This one-component reagent has been proving its capabilities in volumetric titration for more than 35 years in a large range of applications in the most diverse fields of research and industry. Ongoing development work has achieved significant improvements to this reagent.
Advantages include:
• High 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 reduces the formation of crystals which can interfere with the titrator’s performance.
The crystallization of the reagent was occasionally observed under the influence of airborne moisture and also after prolonged residence of the reagent in the Karl Fischer titrator‘s tube system. This effect is mostly prevented by a new and improved formulation.

HYDRANAL VOLUMETRIC ONE-COMPONENT TITRATION – MEDIA
With one-component reagents the medium (i.e. the solvent required) is chosen
according to the dissolution and chemical properties of the sample substance
being analyzed. The most commonly used medium is dry methanol.
The speed, time taken and accuracy of the Karl Fischer reaction is influenced by the medium used in the titration vessel.
