Hydranal, Auxiliaries for Karl Fischer Titration, Honeywell

Solubilizers
Karl Fischer titration is applied to multifarious substances. The nuances in sample properties influence the Karl Fischer titration differently. There are a number of ways to adjust the working conditions in order to enable a direct titration of the sample and avoid complicated and error-prone pre-dissolution and pre-extraction steps. In some cases the addition of solubilizers is recommended.

Buffers
The Karl Fischer reaction is pH dependant, with pH 5-7.5 being the ideal range. Strongly acidic samples slow the reaction and must be neutralized without inducing an alkaline reaction of the working medium prior to starting the titration. Strong bases can increase the pH of the working solution if the basicity exceeds the buffering capacity of the reagent. A titration end point will not be reached. Strong bases also must be neutralized prior to starting the titration.

HYDRANAL-Moisture Test Kit
For rough measurements without a titrator, special test kits for visual water determination according to Karl Fischer can be used. The set contains syringes, titration vessel and reagents: 2 x 500mL Hydranal-Solvent E, 100mL Hydranal-Titrant 5E and 100mL Hydranal-Standard 5.0. Refills can be ordered separately. Contact MG Scientific's Customer Service or your MG Scientific Rep for details.
