Coulometric KF Titration

Coulometric Karl Fischer Titration

Coulometric reagents based on different solvent compositions serve to support the broad variety of samples analyzed.
Some working techniques are supported by special reagents:

  • Hydranal Coulomat AG-Oven for the KF titration with the oven
  • Hydranal Coulomat AD for the cell without diaphragm

Advantages of Hydranal coulometric reagents:

All your KF reagents from one source

33
  • Easy to use
  • High accuracy for trace amounts of water
  • Stable conditions of the titration vessel
  • Broad product range
  • Long shelf life (up to five years)

Hydranal-Coulomat A-type or E-type reagents are used as anolytes. The anolytes contain iodide and a sulfur dioxide/imidazole buffer in suitable solvents.

Hydranal-Coulomat CG reagents are used as catholytes.
