Result - Xylem SI Analytics TitroLine 7500 KF Mode D'emploi

For an automatic titration, you can select from the following modes:
• KF titration
• Dead Stop titration
4.6.1.1 KF and Dead stop titration
KF titration is a specific form of dead-stop titration. In normal dead-stop titration, titration is to the specified value
in µA, which must be maintained for a defined time. In KF titration, this still occurs, but a specified drift criterion in
µg/min must also be met. With KF titration, a conditioning step is also is preset in order to eliminate any moisture
in the titration vessel and the solvent.
The first stage of the Dead stop and KF titration consists in the continuous dosing up to a delta value away from
the set end point. The dosing speed can be adjusted. Subsequently, titration is performed with linear step sizes
between the delta value and the end point.
The following titration parameters can be set for the dead-stop and KF titration:
Titration parameter
µA-Endpoint
Delta µA-value
Linear steps in ml
Endpoint delay in s
Delay time (between linear steps)
Start delay time /extraction time
Conditioning on/off
Pre - titration in ml
Polarization voltage in mV
Minimum und maximum titration time in s
Max. titration volume
Drift in µg/min
Dosing speed in %
