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)

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.
