Chlorophyll Detection with Algae Class Differentiation
Innovative spectral fluorometers with integrated algae class differentiation enables the simultaneous determination of green alge, cyanobactria, brown algae and cryptophytes. Available in different versions for the laboratory, in the measuring station and in the water body.
Fluorescence
The chlorophyll fluorescence of living algae cells (in vivo) can be used easily to determine:
- chlorophyll content
- photosynthetic activity
The advantages of in vivo fluorescence measurement are:
- high sensitivity
- no sample preparation
- rapid performance
- low costs
Interference can occur with compound such as:
- CDOM (coloured-dissolved organic matter), yellow substances
- accessory algal pigments
- large amounts of turbid particles
bbe spectrofluorometers for the measurement of micro-algae, picoplankton, nanoplankton and benthic algae:
- use the advantages of in vivo fluorescence measurement
- correct for CDOM
- determine the effects of accessory algal pigments
- calculate the chlorophyll-a of up to 5 different algae classes
- determine the transmission
- determine the photosynthetic activity
bbe spectrofluorometers are used for practical work in:
- drinking water monitoring
- monitoring of reservoirs & rivers
- environmental/ecological assessment
- monitoring of lakes for bathing
- algal bloom detection
- marine research
- limnological research
- education
bbe spectrofluorometers are for:
- vertical and horizontal profiling - the FluoroProbe
- continuous submersed monitoring - the FluoroProbe
- tracer measurement - the FluoroProbe
- sediment screening - the BenthoFluor
- online flow-through measurement - the AlgaeOnlineAnalyser
- laboratory use - the AlgaeLabAnalyser, FluoroProbe, AlgaeOnlineAnalyser
- rapid detection of cyanobacteria e.g. in bathing water - the AlgaeTorch
