Zusammenfassung:	The invention relates to a method and to an apparatus for optical emission spectroscopy of fluids. The method comprising conducting a fluid sample flow (1) in a conduit (2) having an inclined conduit section (3), wherein the conduit (2) limits a flow channel (4) for the fluid flow, conducting at least a part of the fluid sample flow (1) vertically downwards from an outlet (5) of the inclined conduit section (3) of the conduit (2) to a flow cell (6). The method comprises providing the inclined conduit section (3) of the conduit (2) upstream of the outlet (5) with a turbulence generator (13) to change the cross section of the flow channel (4) of the conduit (2), and by providing the turbulence generator (13) at a distance from the outlet (5).
