Karl Fischer Titration<br />
<strong>Honeywell</strong> offers a wide range of pyridine-free Karl Fischer<br />
reagents for both volumetric and coulometric titrations for nearly<br />
all types of samples, completed by a broad range of standards.<br />
Coulometry<br />
Coulometric reagents based on different<br />
solvent compositions serve to support<br />
the broad variety of samples analyzed.<br />
Furthermore, some working techniques are<br />
supported by special reagents i.e. the use of<br />
Karl Fischer oven by Hydranal-Coulomat<br />
AG-Oven or the use of a cell without<br />
diaphragm by Hydranal-Coulomat AD.<br />
Volumetry<br />
The new formulation of<br />
Hydranal-Composite reagents improves<br />
the stability and eliminates the formation of<br />
crystals which can interfere with the titrator’s<br />
performance. Besides the most commonly<br />
used medium, dry methanol, also<br />
Hydranal-Methanol Rapid containing<br />
accelerators, less toxic ethanol based media<br />
(E-type) as well as methanol-free media for<br />
ketones and aldehydes (K-types)<br />
have been developed.<br />
Water Standards<br />
Hydranal-Water Standards are designed<br />
for calibration, validation and inspection of<br />
analytical instruments and reagents. With the<br />
double accreditation (ISO/IEC 17025 and ISO<br />
Guide 34), Hydranal introduced the very<br />
first commercially available CRM<br />
(Certified Reference Material)<br />
Water Standards for Karl Fischer titration.<br />
