‘End-point titration’ Titration parameters
When working with end-point titration, there are some differences in context with linear and dynamic
equivalence-point titration.
As was already described in
Chapter 4.5.2.3
, end-point titration, in a first stage, proceeds by
continuously dosing until a specific Delta value (“
Delta end-point
”) at a distance from the set end
value is reac
hed. The dosing speed of this first stage can be set in terms of % on the “
Dosing
parameters
” menu. Subsequently, titration continues in a drift-controlled manner or with a fixed
holding time with a linear step width between the Delta value and the end value. As soon as the end
value has been reached, a defined waiting time is observed. If the end value is fallen short of, one or
more than one additional titration step(s) is/are added until the end value has become stable. The
waiting time at the end is referred to as
End-point delay
.
In the case of an end-point titration for two endpoints, it is possible to set both of the endpoints with
different Delta values and end-point delays:
