HYDRANAL – Water-in-methanol 5.0 is a volumetric Karl Fischer titration reagent that contains 5.0 mg of water per milliliter, dissolved in methanol. This reagent is used to determine the water content in various samples using the Karl Fischer titration method, particularly for samples with relatively low water content.
Karl Fischer Titration:
The Karl Fischer titration method is an analytical technique used to determine the water content in a sample.
Titration Reagent:
HYDRANAL – Water-in-methanol 5.0 is one of the components of the Karl Fischer titration system. Other components typically include a solvent (such as methanol or ethanol) and a standard solution.
Composition:
This reagent contains water dissolved in methanol, with a concentration of 5.0 mg of water per milliliter of solution.
Application:
This reagent is suitable for titrating samples with relatively low water content, due to its high sensitivity to the presence of water.
Importance:
Using the appropriate reagent in Karl Fischer titration is crucial for obtaining accurate and reliable results in water content determination of a sample.
