HYDRANAL-Titrant 5 two-component reagent, based on methanol, titer ~5 mg/ml, glass bottle with RFID chip, Smart Chemical for OMNIS, 6 x 1 L

Two-component reagents have been specially developed to take advantage of the high titer stability of a pure iodine solution. In addition to this advantage, they offer a very fast titration process through the use of ideally buffered solvent systems.
Composition
With two-component reagents, the Karl Fischer reactants are divided into two solutions: the titrant and the solvent. Hydranal-Titrant contains iodine in a precisely defined concentration dissolved in an alcohol. Hydranal-Solvent is an alcoholic solution of sulfur dioxide and imidazole. The alcohol used for this is either methanol for the standard reagents or ethanol for the E types. Other solvent types based on different solvent mixtures enable individual adaptation to the requirements of specific sample materials.
Advantages of the HYDRANAL two-component reagents:

• High titration speed
• Ideal accuracy for small amounts of water
• High buffering ability
• Accurate and stable titer
• E-type reagents: reduced toxicity compared to methanol
• Long shelf life (three years for titrants, five years for solvents)
