Quick analysis of chlorophyll and phycocyanin

Depth-profile with quick analysis of chlorophyll and unbound phycocyanin concentrations as well as algae classes

The bbe PhycoProbe* is a highly sensitive measuring instrument for the in vivo analysis of chlorophyll-a in real microalgae and blue-green algae (cyanobacteria). Individual profiles for the different algal classes are created during the measurement. The algal content is determined by evaluating the chlorophyll fluorescence in real time. Without the necessity of using a laboratory, it is possible to completely analyse the occurrence and distribution of algae in different water bodies, if necessary at different depths.

Additionally, the PhycoProbe measures the amount of unbound phycocyanin (free PC) which reflects the release of blue-green algae contents like toxins as well as flavours and odorous substances. Interference from e.g. humic substances is compensated using the integrated yellow substances measurement.

Databased bbe++ Software

The bbe PhycoProbe software supplied with the instrument facilitates detailed data analysis. All measurement data can be displayed numerically or graphically. Sections of data measurements can be recorded and printed using the zoom function. Data can also be exported to a spreadsheet program (e.g Excel). All settings and calibrations are performed by the software.

Hydro-Wiper unit to prevent biofouling

The FluoroProbe can now be operated on moored platforms, submersed from buoys or fixed measuring stations using the Hydro-Wiper (made by Zebra-Tech Ltd, NZ). The wiper brushes can be set to periodically clean the lenses of the measuring chamber to remove biofilms and dirt which builds up over long periods of operation.
