The principal function of the Titrator is to allow zeta potential, size or intensity measurements to be made, while adding quantities of additives (titrants) to the sample when performing a particular titration type, i.e. pH, Dilution or Additive. This allows the effect of adding these titrants on the measurement to be investigated.
The heart of the titrator is the dispenser unit. The sample to be measured is placed in a disposable sample container. The dispenser unit has an internal pump that circulates the sample through the cell in the optical unit (A size flow cell will be required if size measurements are to be made). The dispenser unit has three titrant containers that can be filled with either an acid, base or some other additive. The titrants used can be different concentrations of the same acid or base. This will improve the accuracy of obtaining a target pH or concentration and limit the quantity of titrant used. The syringe system can deliver a precise quantity of titrant from one of the titrant containers into the sample container.
