Controlled dosing
Titration to preset end-point.
The reagent addition is controlled
such that a preset measured
value is adhered to as accurately
as possible.
The dosing function is controlled
such that a nominal measured
value is adhered to as accurately
as possible. The nominal meas-
ured value follows a linear ramp.
Volume that has been dispensed
up to the endpoint (EPX in mL).
Evaluation of
•
rates dV/dt in the set time
windows and the mean rate
over the entire measuring
point list.
•
volumes associated with a
preset time (fix V).
•
times associated with a
preset fraction of the total
volume (fix time).
The total volume (C41) and the
time needed for dosing (C42)
can be used for calculation.
•
For rapid, quantitative deter-
minations in analytical chem-
istry. Requirement: EP of the
titration reaction is known
and does not change during
a determination series.

If an excess of titrant must be
avoided.
