Abstract:
A particle detection system with a detection mechanism that includes detectors positioned to detect two different ranges of fluorescence produced by particles in the fluid in a flow chamber. Each of the detectors is arranged to generating a trigger signal whenever fluorescence is detected. The system and related method enhance the accuracy and sensitivity of blue-green algae monitoring by utilizing imaging flow cytometry combined with particle analysis and the measurement of the ratio of each particle's phycocyanin to chlorophyll b detected by using the two detectors configured for detection of two different fluorescence ranges, one associated with the phycocyanin and the other associated with the chlorophyll b. Optionally, captured images may be used in comparison to known images of a library of images.
