Reagents for Volumetric Karl Fischer Titrators

A word about Volumetric reagents, titrants, and solvents:

"Composites" are referred to as one-component where as "Titrants" are referred to as two-component.  What exactly does that mean?

  • One-component reagents or "composites" have everything necessary for the titration of water.  All that is required beyond the composite is an ordinary methanol solvent inside the titration vessel to inject sample into for testing.  Over time water will lessen the strength of the composite and therefore it will be important to update the composites factor or "strength" from time to time.
  • Two-component reagents or "Titrants" have separated some of the reagent components out and into the solvent.  In this case a specific solvent must be used to work with the Titrant for everything to function correctly.   A benefit of this is that the titrant only becomes active once combined with the specific solvent.  This helps provide longer stability and life of the reagents.
