METHODS
2nd Derivative:
When second derivative is used to recognize the equivalence point, the titration curve inflec-
tion point (EQP) is the point where the second derivative crosses zero.
The detection algorithm looks for the point where the second derivative changes sign.
The checked point, or first derivative, must be greater than the threshold value (see
Recogni-
tion Options
on page
5-17).
5.5.7 Recognition Options (Equivalence End Point (pH or mV) only)
The
Recognition Options
screen is a set of parameters used to avoid false detection of
the equivalence point due to the chemical system (titrant / sample species and concentra-
tions) and / or electrode response.
The
Recognition Options
screen is available only when
Equivalence End Point (pH or mV)
option is selected.
