Automatic titration by stepwise addition of equal volumes of titrant. Part II. An automatic titration system

A fully automatic titration system is described. The system carries out transfer of the sample by pipette, and dilution, titration and washing of electrodes and titration vessels. Titrations are performed by adding titrant stepwise in equal volumes to the sample, with recording of potential after each addition. These results are used to calculate equivalence points. The system has a loading capacity of 200 samples, and an analysis rate of up to 30 samples per hour.
