Abstract

The present invention relates to a method for titration comprising guiding a sample to be titrated through a conduit, adding a reagent to said conduit at at least two entrance positions along said conduit in such a manner that said reagent will react with the sample within at least one individual sector of the conduit, defined as the space between two consecutive entrance positions or a final individual sector defined between a final entrance position and a sample exit point of the conduit, while at least one detection device positioned at the end of each sector of said conduit register the chemical and/or physical status. A pressure difference is provided between the reagent delivery device and the sample conduit such that the pressure difference measured between the reagent delivery device and the end of the final individual sector is controlled to be greater than the total pressure drop between the sample delivery point and the end of the final individual sector. The invention further relates to an arrangement for carrying out said method.
