HYDRANAL Coulomat AG 500ml About

• Hydranal Coulomat AG is a methanol-based anolyte solution used in coulometric Karl Fischer (KF) titration for water content determination. It's designed for use in cells with or without a diaphragm and is known for its quality and reliability in the Hydranal brand. Here's a more detailed description:
  • Function:Coulometric KF titration relies on the reaction of iodine with water, which is generated electrochemically in the titration cell. Hydranal Coulomat AG serves as the anolyte, the solution in the anode compartment of the cell, containing the necessary reagents for this reaction.
  • Composition:It's primarily composed of methanol, imidazole, sulfur dioxide, and diethanolamine.
  • Suitability:It's suitable for use in cells with or without a diaphragm, making it versatile for various sample types and titration setups.
  • Key Properties:
    • pH: 5.0-6.0, which is optimal for accurate water determination.
    • Density: 0.930 g/cm at 20C.
    • Boiling Point: 63C.
    • Flashpoint: 14C.
  • Safety:It's a flammable liquid and classified as a hazardous substance due to its toxicity and potential to cause serious eye damage. Appropriate safety precautions, including wearing protective gear and working in a well-ventilated area, are essential.
  • Storage:It should be stored at ambient temperature.
  • Brand:Hydranal is a well-known brand for Karl Fischer titration reagents, recognized for its quality, consistency, and comprehensive product range.
