Combined flow titrator used for carrying out volumetric as well as coulometric titrations in the chemical, biotechnology, pharmaceutical and food industries comprises two controllable pumps connected to an electrolytic cell

摘要

Combined flow titrator comprises two controllable pumps (P1, P2) for transporting reagent solution and diluting agent and for producing concentration gradients via switching valve connected to electrolytic cell for producing reagent and bypass channel (B). (P1, P2) are connected to flow-through reactor (DR) pumping sample solution so that either cell or bypass channel is opened for flow. Preferred Features: One pump for the transport of an electrolyte to the cell is controlled so that the electrolysis current can change linearly.
