Abstract

A cell for conducting electrochemiluminescence measurements is disclosed. The cell in one embodiment provides a measurement cell housing having a cavity, a fluid inlet channel for inducing fluid into the cavity and a fluid outlet channel for discharging fluid from the cavity at axial ends. The cell also provides at least one working electrode and a counter electrode on or in the cavity, and an optical viewing element for observing electrochemiluminescence effects in the cavity, wherein the fluid inlet channel has an at least approximately continuous curved course in a transition area to the cavity so that the fluid inlet channel at its end which is joined to the cavity is shaped in such a manner as to constitute a continuous course of the transition between the fluid inlet channel and the cavity to generate a largely steady flow profile when inducing fluid into the measurement cell cavity.
