AlgaeOnlineAnalyzer

bbe algae online analyzer

Chlorophyll, algae class and photosynthetic activity-continuous determination in real time

Applications

  • Regulatory control
  • Environmental monitoring
  • Limnological work
  • Research and education
  • Supervision of aquaculture

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.

Product Features

  • Online chlorophyll analysis for measuring stations as well as for laboratory use
  • Simultaneous determination of chlorophyll concentration, photosynthetic activity of chlorophyll and transmission
  • Determination of different algae classes by excitation using coloured LEDs; calculation of the content of green algae, blue-green algae (cyanobacteria), brown algae (diatoms and dinoflagellates) and cryptophytes

  • Batch mode:
    instrument can be switched from flow-through measurement to single measurement mode for laboratory operation

AlgaeGuard

bbe algae guard

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.

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.

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.

Rugged Transport Case

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.
