Chlorophyll, algae class and photosynthetic activity-continuous determination in real time
Applications
The fluorescence of algae via excitation by visible light mainly depends on the chlorophyll-a, a common pigment in the plant world. The presence of other pigments indicates different algae classes. The interaction of these different pigments with chlorophyll-a results in a special excitation spectrum for taxonomic algae classes.
The special patterns of this algal fluorescence – so-called fingerprints – are used in bbe fluorometers for the qualification of different algae classes. The light sources for the excitation are LEDs with selected wavelengths. The fingerprints of four algae classes and for yellow substances are pre-defined in the instrument. However, user-specific fingerprints can also be defined.
The physiological performance of the algae (algae activity) on photosynthesis is determined by exitation using additional background light. The resulting variable fluorescence allows the calculation of algae activity given as the Genty parameter. This Genty parameter represents the quantum yield and is also an expression of the vitality of the algae.
Continuous, cost-effective chlorophyll analysis with cleaning device. Detection of green algae, cyanobacteria, diatoms and cryptophyceae
The AlgaeGuard is designed as a “plug and play” instrument, i.e. measurements are carried out automatically using pre-defined parameter settings immediately after boot-up or by pressing the start button on the touchscreen panel. Continuous configuration by the operator is not necessary. Maintenance is as low as 1 hour per month. Parameters can be changed using the external bbe PC software if necessary.
