Automated titrators from METTLER TOLEDO follow a defined sequence of operations. This sequence is basically the same for all different models and brands. It is performed and repeated several times until the endpoint or the equivalence point of the titration reaction is reached (titration cycle). The titration cycle consists mainly of 4 steps: Titrant addition Titration reaction Signal acquisition Evaluation   Each step has different specific parameters (e.g. increment size), which have to be defined according to the specific titration application. More complex applications require more steps, e.g. dispensing of an additional reagent for back titrations, dilution, adjusting of the pH value. These steps and the corresponding parameters are resumed in a titration method.
