AlgaeLabAnalyzer

bbe algae lab analyzer

An instrument for chlorophyll and photosynthetic activity measurement in the laboratory

Applications

  • Waterway analysis and assessment
  • General environmental management
  • Intake monitoring
  • Chemical analysis
  • Toxicity testing
  • Waste detection
  • Dam monitoring
  • Limnological work
  • Research and education

The fluorescence of algae via excitation with visible light mainly depends on the chlorophyll-a, a pigent wide-spread in the plant world.  The presence of other pigments is typical for different algae classes.  The interaction of these different pigments systems with chlorophyll-a result in a special excitation spectrum for taxonomic algae classes.

The special patterns of 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, special user-specific fingerprints can also be defined.  The determination of algal activity (Genty parameter) is performed using additional background light.

Product Features

  • Simultaneous determination of chlorophyll concentrations, photosynthetic activity of chlorophyll and transmission
  • The detection of different algae classes via excitation using different coloured LEDs; calculation of biomass on green algae, blue-green algae, brown algae (diatoms and dinoflagellates) and cryptophytes
  • Direct measurement without sample preparation via filtration, dilution or stirring etc.
  • Results of photosynthetic activity of the chorophyll usng different excitation patterns; the common fluorescence signals  are used via the Genty parameter method
  • Yellow substances (CDOM) measurement to correct the calculation of total chlorophyll
  • Integrated stirrer unit – no problems with sedimentation during long-term measurements

PhycoLabAnalyzer

Early warning system for detection of cyanotoxins, flavours and odorous substances

Early warning system for detection of cyanotoxins, flavours and odorous substances in raw water

Rugged Transport Case

NEW! Phycocianin measurements – The indicator for cyanotoxins as well as flavours and odorous substances

The bbe PhycoLabAnalyser* (PhycoLA) offers the simultaneous determination of chlorophyll concentrations, transmission, and – as an option – the photosynthetic activity of microalgae in a 25 ml glass cuvette. Additionally, the PhycoLA 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.

The chlorophyll and phycocyanin content is excited by coloured LEDs and allocated to the different algal classes. The PhycoLabAnalyser enables direct measurement without sample preparation by filtration or solvent. The fluorescence signals f0, f, and fm are used to calculate the photosynthetic activity using the Genty parameter method. A yellow substances (CDOM) correction is also used to correctly calculate the total chlorophyll content. The device is virtually maintenance-free and very simple to operate thus saving both time and money.
