The invention relaters to a device (100) for biological analysis by measurement of photoluminescence in a fluid in a measurement tank (111). This device (100) comprises at least two light sources (121, 131) adapted to emit in different spectral areas respectively appropriate for measurement of absorption and fluorescence, and a sensor device (140) comprising a sensor (141), an optical system (142), and filter means (144), which three elements are mutualized in accordance with the invention to enable absorption and/or fluorescence to be measured. In accordance with the invention the internal gain of the sensor (141) is configurable to enable the fluorescence and absorption measurements to be executed sequentially.
A device (100) for biological analysis by electro-optical measurements on a fluid in a measurement tank (111), said device (100) comprising at least two light sources (121,131) configured to emit in different spectral areas respectively appropriate for measurement of absorption and fluorescence, a means for measuring the impedance associated with each absorption and fluorescence measurement, and a shared detection means (140) comprising three elements being mutualized to enable absorption and/or fluorescence to be measured, said three elements being a sensor (141), an optical system (142), and filter means (144), the internal gain of the sensor (141) being configurable to enable the fluorescence and absorption measurements to be executed sequentially.
