摘要
In a method and a device for laser induced fluorescence detection in liquid chromatography a light beam (1) is directed from a laser source (2) towards a liquid flowing in a chosen flow direction for the detection of the presence of one or several substances. At a flow point illuminated by the light beam (1) the liquid is brought to emit a fluorescence radiation (3) which is received by a receiving unit (6). The light beam (1) is directed substantially perpendicularly to the flow direction of the liquid. The liquid is brought to pass the illuminated flow point in the form of a column with an accurately defined surface. The fluorescence radiation (3) is received in a direction which deviates from directions emanating from the illuminated flow point perpendicularly from the flow direction of the liquid column.
