28.1 Coulometric Karl Fischer titrations (KFC)
28.1.1 Control parameters
The control parameters for the endpoint are defined under [Control
parameters].
Endpoint at
Measured value for the endpoint.
The values that are actually measurable may vary from the values specified
here, depending on the hardware. The binding measurement value ranges
can be found in the manual, in the "Technical specifications" chapter.
Input range –1250.0 - 1250.0 mV
Default value 50.0 mV
Selection off
Titration rate
Three predefined sets of parameters can be selected for the titration rate.
Selection slow | optimal | fast | user
Default value optimal
slow
For samples with a low water content or samples which release their
moisture only slowly.
optimal
For all standard titrations. The parameters have been optimized for the
most frequent applications.
fast
For uncritical samples with high water content.
user
The individual titration parameters can be modified.
The settings of the individual titration rates are listed in table 9, page 221.
