Fig. 73 a
The following calculation formulae are available for automatic titration mode:
Formula
EP
(EP-B)*T*M*F1/(W*F2)
(W*F2)/(EP-B)*M*F1)
The abbreviations used here have the following meaning:
EP: Consumption at the end point in ml
B: Blank value in ml. Mostly determined by way of titration
T: Titer of the titration solution (e.g. 5.012)
M: Mol; mol- or equivalence weight of the sample
F1-F5 Factor 1-5. conversion factors
W "Weight", weighed-in quantity in g or volume in ml."
Additional information
Formula for calculating only the ml
consumption
Formula for calculating the
concentration of a sample taking into
account a blank value in terms of ml.
Formula for calculating a titer (T) of a
titration solution.
