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.

Continuous flow titration

A device for detection of one or several fluorescent species, said species being contained in a medium, said medium being contained in a conduit, said device comprising a means of exciting the fluorescent species by light, said medium and conduit making up a structure that is transparent to the exciting and the emitted fluorescent light, and said device comprising one or several such structures, may be improved by letting at least part of the emitted fluorescent light be guided away from the illumination zone by total internal reflection (TIR) in said structure and collected from one end of said structure.

Device for detection of fluorescent species

An integrated microfluidic element (,) composed of two juxtaposed plates (,) bonded together, wherein at least one plate (,) has an etched structure or pattern of channels (,) on the surface facing the other plate (,) to form sealed micro channels (,), said element having micro spacers or posts (,) distributed over the etched surface of said one plate outside of said etched structure or pattern, and walls (,) surrounding said channels (,), said walls (,) having a height equal to that of said spacers or posts (,); and a method for the manufacture of such integrated microfluidic element.
