EQ1
The abbreviations used here have the following meaning:
ml: Total consumption, e.g. for pH Stat
S: Slope in ml/time (pH Stat)
EQ: Consumption at the equivalence point 1 and 2 in ml
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. 0.09986)
M: Mol; mol- or equivalence weight of the sample (e.g. NaCl 58.44)
F1 - F5 Factor 1 - 5 conversion factors
"Weight", weighed-in quantity in g or volume in ml
W
