Result

At first, the calculation options are specified (dynamic and linear titration only):

Fig. 61

One inflection point (1 EQ) can be analyzed in the TitroLine

5000:

Fig. 62

With „

only total consumption

“ the consumption at the last measured pH/mV value will be used.

With „

1 EQ

“respectively the calculated equivalence points of the titration curve will be used.
