Abstract

The sample stream of the automatic titrator flows from syringe 1 at a constant rate. The reagent stream from syringe 2 has a flow rate which increases linearly with time. Syringes 1 and 2 are filled with a sample and reagent through valves 9 and 10 respectively. Cam 7 drives piston 12 at a constant speed. Cam 8 varies the speed of piston 13 so that such speed increases linearly with time. The two fluids from syringes 1 and 2 are mixed at chamber 3. The mixed fluids are passed between light source 4 and optical filter 5. The optical density of the mixture is measured by photocell 6 to indicate the end point of the titration. When the end point is reached, timer 11, which is started at the beginning of the titration cycle, is stopped. Resetting of timer 11 permits a new titration cycle to begin.
