Patent ID: 7153695

Claim:
A method for continuous flow titration comprising the steps of: continuously delivering a sample to be titrated through a conduit via an inlet at a sample delivery point on said conduit using pressure, adding at least one reagent to said conduit by means of a delivery device at at least three entrance positions along said conduit in a consistent and defined amount, wherein the consistent and defined amount is provided by creating such pressure difference between the reagent delivery device and the sample conduit that the pressure drop within the conduit becomes insignificant for the results of titration, specifically the pressure difference between the reagent delivery device and the end or near the end of the final individual sector is between 1.5 and 1000 times greater than the total pressure drop within the conduit, that is the pressure drop between the sample delivery point and the end or near the end of the final individual sector; and determining a titration endpoint.
