>evaluation
EPC
EP recognition:
fix EP1 at pH
pK/HNP:
Endpoint criterion.
Type of EP recognition: all EP's, only
greatest EP, only last EP, only EP's in
windows, no evaluation. If ”window” is
selected, lower and upper limits of
windows are inquired.
Interpolation of volume at given pH, U, or I,
resp. Up to 9 fix EP's.
Evaluation of pK or half neutralization
potential (HNP).
