HYDRANAL™ – Solvent
HYDRANAL™ – Solvent is an alcohol-based solution containing sulfur dioxide and imidazole, used as the solvent component in Karl Fischer titration, particularly in two-component volumetric methods. There are two main types of HYDRANAL solvents: one based on methanol (for standard reagents) and the other based on ethanol (for E-type reagents).
Karl Fischer Titration:
HYDRANAL-Solvent is part of the Karl Fischer titration system, a widely accepted standard method for determining water content in a wide variety of samples.
Components:
This solvent contains sulfur dioxide and imidazole, which work together to react with the water present in the sample.
Types of Solvent:
There are two types of HYDRANAL solvents, distinguished by the type of alcohol used:
-
Methanol-based (for use with standard titrants)
-
Ethanol-based (for use with E-type titrants)
The choice of solvent depends on the titrant type and the nature of the sample being tested.
Function:
HYDRANAL solvent serves to:
-
Dissolve the sample, and
-
Facilitate the reaction between the water in the sample and the titration reagent (usually iodine)
to achieve a precise titration endpoint.
Adaptation:
Other HYDRANAL solvent variants, with different solvent mixtures, are available to meet the specific requirements of diverse sample types.
