Essential components of an automatic titrator

A titration system ueually consists of the elements depicted In Fig. 13.1, namely (a) tltrant delivery system, (b) titration vessel, (c) titration monitor and (d) control section. 

Reagent dispensers are chiefly volumetric or coulometric In nature. Formerly, the automation of coulometric titration procedures developed at a higher speed than that of volumetric titration —this was probably a result of the ease with which the current intensity used for reagent generation could be regulated by means of relatively simple electronics. 

The commonest automatic titrators used in the laboratory are burettes, which can be classified according to their operational foundation Into (a) burettes with automatic valves, (b) automatic syringe burettes and (c) other types of automatic burette.
