HYDRANAL™ – Solvent CM
HYDRANAL – Solvent CM is a solvent used in Karl Fischer titration, specifically designed for two-component volumetric titration. It is an alcoholic solution containing sulfur dioxide and imidazole. The alcohol used can be methanol (for standard reagents) or ethanol (for E-type reagents), depending on the sample requirements. Other solvent variants with different compositions are also available to accommodate specific sample needs.
Function:
HYDRANAL – Solvent CM acts as the reaction medium, enabling the chemical interaction between sulfur dioxide, iodine, and water (the analyte) in the presence of a base (typically imidazole). This reaction allows for the quantitative determination of water content in the sample via titration.
Used in two-component volumetric Karl Fischer titration:
This means the titration process involves two reagents — an iodine solution (the titrant) and a solvent solution containing sulfur dioxide and a base.
Contains alcohol:
Alcohol (methanol or ethanol) serves as the primary solvent in the reaction.
Contains sulfur dioxide and a base (imidazole):
These two components are essential to the Karl Fischer reaction, enabling the oxidation of water.
Adaptable:
Alternative solvent types are available, allowing customization to match the solubility characteristics of specific samples.
