Evaluation of pK value / half neutralization potential

In non-aqueous solutions the half neutralization potential (HNP) is fre-
quently used instead of the pK value. The HNP is evaluated in the same
way as the pK value.

No parameters can be edited for the command EVAL pK/HNP.

NOTE

If a start volume is to be added then it must be smaller than the half
endpoint volume.

Minimum and maximum evaluation (EVAL MIN/MAX)

For the minimum or maximum measured value the associated volume,
time and temperature are interpolated from the measuring point list. The
evaluation begins as soon as the slope of the curve exceeds a particular
threshold value.
