Online determination of algae classes, chlorophyll and phycocyanin concentrations as well as photosynthetic activity

The bbe PhycoSens* is deployed in measuring stations and laboratories in which online measurement of water quality is required for rivers, reservoirs, dams and lakes as well as in drinking water production.

The instrument impresses due to its rapid analysis of chlorophyll and unbound phycocyanin (free PC) concentrations. The free colour pigments of the cyanobacteria are an important indicator for cyanotoxins as well as flavours and odorous substances in raw water. The online device can also measure the photosynthetic activity of microalgae and the transmission. The detection of different algal classes by excitation with coloured LEDs distinguishes this measuring instrument from its competitors. Part of the analysis is a yellow substances (CDOM) measurement to adjust the calculation of the total chlorophyll and phycocyanin contents. The integrated cleaning unit protect against growth problems during long-term measurement.
