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)
Factor 1 – 5 conversion factors
F1 - F5
"Weight", weighed-in quantity in g or volume in ml
W

EQ2 and EQ1 including one multiplicative
factor F1
For pH Stat: only total consumption
For pH Stat: formula for total consumption
taking into account the sample amount
and further factors
For pH Stat: formula for calculation of the
slope in ml/s taking into account of
calculation factors incl. weight/pattern.
