摘要
Disclosed is apparatus (1) for measuring fluorescence and absorbance of a substance in a sample, said apparatus (1) comprising: a flow cell (2) for containing a sample, a first light source (3), a first conductor (5) for transmitting light from the first light source (3) to the flow cell (2) for irradiating a sample contained therein, a second conductor (7) for transmitting light from the flow cell (2) to a sample detector (9) arranged to detect an electromagnetic radiation that has passed through said cell (2), and a processing unit (16) arranged to receive a first signal (31) from a reference detector (15) and a second signal (32) from the sample detector (9) and to determine an absorbance based on said first and second signals (31,32), said apparatus (1) further comprising a second light source (4), a third conductor (6) for transmitting light from the second light source (4) to the cell (2) and wherein the sample detector (9) is further arranged to also detect fluorescence signals in the light that has passed through the flow cell (2). The invention also relates to a method for measuring the absorbance and the fluorescence of a substance in a sample.
