The basic module is the essential device for
microcoulometric water determination according
to Karl-Fischer-Titration in liquid samples and gases.
This coulometric titration is based on the
electrochemical generation of the iodine
needed for the determination.
There is no need for any working with titer of KF-reagent
and their adjustment.
The optimized measuring cell allows very low
background drift and short preconditioning times.
Therefore the coulometric method can be used as
a down to trace ppm-analysis.
The sample to be analyzed is injected right into the
measuring cell.
The titration current is adjusted automatically and
continuously to the amount of water. Short measuring
times are realized.
Measuring cells without diaphragm can be used. Many
applications do not require a diaphragm, so only one
coulometric reagent is needed.
All customary KF-reagents are suitable.
The basic module can be upgraded with additional
modules available on request.
