Organic Acids)
FOS/TAC-value
The abbreviations used here have the following meaning:
ml: Total consumption, e.g. for pH Stat
EQ: Consumption at the equivalence point 1 in ml
EP: Consumption at the end point 1 and 2 in ml
B: Blank value in ml. Mostly determined by way of titration
T: Titer of the titration solution (e.g. 0.09986)
M: Mol; mol- or equivalence weight of the sample (e.g. NaCl 58.44)
F1-F5 Factor 1-5. conversion factors
W “Weight“, weighed-in quantity in g or volume in ml.”
