Continuous single-batch titration is the traditional, manual approach where titrant, held in a dispensing tool with high volumetric accuracy such as a burette, is continuously added to a test solution containing the analyte. The cumulative volume of titrant added at the endpoint yields the concentration of the analyte. This process is single-batch because each successive ratio of titrant:analyte exists in the same volume -unique ratios are separated temporally but not spatially. The flow analogue of this experiment is flow injection titration . Separating samples spatially can be achieved in discrete batch titration, where each sample container holds a different ratio of titrant:analyte. The advantage of this technique is that the characterisation of the endpoint is generally less dependent on the speed of measurement. A second advantage is that throughput of discrete batch titration can be increased by using a discrete flow titration, where each unique ratio is continuously generated, typically by syringe pumps, and the endpoint is detected inline .
