A device for inspecting a biological fluid, including a channel through which the fluid flows, a first inspection module arranged in a first region of the channel, and a second inspection module arranged in a second region of the channel, the device configured to provide a quantity that is representative of output of the second inspection module. The first inspection module is configured to measure at least one electrical property of the fluid passing through the first region. The second inspection module is configured to measure at least one optical property of the fluid passing through the second region. The inspection device also includes a controller connected to the first inspection module and to the second inspection module and configured to control the second inspection module according to the output of the first inspection module.

Device for inspecting a biological fluid

The invention relaters to a device () for biological analysis by measurement of photoluminescence in a fluid in a measurement tank (). This device () comprises at least two light sources () adapted to emit in different spectral areas respectively appropriate for measurement of absorption and fluorescence, and a sensor device () comprising a sensor (), an optical system (), and filter means (), 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 () is configurable to enable the fluorescence and absorption measurements to be executed sequentially.
