How can one speed-up the titrant addition (incremental vs. dynamic)?
Incremental titrant addition (INC) The titrant is added in constant volume increments dV. Incremental titrant addition is used in non-aqueous titrations, which sometimes have an unstable signal, and also in redox and in photometric titrations, where the potential jump at the equivalence point occurs suddenly. Notice that in the steepest region of the curve there are relatively few measured points. Dynamic titrant addition (DYN) A constant pH- or potential change per increment allows the variation of the volume increment between minimum and maximum volume increment. Thus, the analysis can be speeded up by using big increments in the flat regions of the titration curve. In addition, more measured points are obtained in the steepest region of the curve leading to a more accurate evaluation.
