Check out the industry standard in online biomonitoring using green algae. Fast & sensitive detection!

bbe Moldaenke GmbH has developed and produced measuring instruments and software to assess and manage water quality for more than 20 years . Made for use in oceanography, limnology, drinking water monitoring, river dam monitoring, bathing water analysis, supervision of aqua culture systems and environmental assessment, these instruments have come to be relied upon as the industry standard.

Algae Toximeter II — Online Biomonitoring Using Green Algae

For the fast and sensitive detection of toxic substances in water

Continuous Monitoring

The bbe Algae Toximeter continuously monitors water for the presence of toxic substances. Standardized algae are mixed with the sample water and the instrument detects the photosynthetic activity of the algae. Damage to the algae, caused e.g. by herbicides, causes a reduction in algae activity and activates an alarm above a pre-defined threshold.

Measuring Instrument

The bbe Algae Toximete r also serves as a measuring instrument for the precise determination of algal concentrations in water. Algae group differentiation applied to the sample water enables the quantitative allocation to different spectral algal classes.

High Temporal Resolution

The bbe Algae Toximeter works with a double test loop for sample incubation, short measuring intervals and a PC for online data analysis, which optionally allows a high temporal resolution of the water to be monitored.

Sample Incubation

An alternative version of the Algae Toximeter enables the incubation of the sample within the measuring chamber without sample loops thus resulting in less maintenance with longer measurement cycles.

Advantages of the Algae Toximeter II

Highly sensitive detection of herbicides and their by-products
Sensitive to a wide range of toxic substances
Controlled independent cultivation of algae
No exclusion period after alarm

Cultivation control due to active chlorophyll measurement
Anti-fouling system due to automatic cleaning of the measuring unit
Autostart function after power failure

Measurements

Direct Chlorophyll Fluorescence: corresponds to wet-chemical chlorophyll analysis
Active Chlorophyll Fluorescence in the Sample (Genty Method): determines the percentage of active chlorophyll under illumination and serves as a toxicity measurement
Differentiation of Fluorometric Algae Classes: to simultaneously determine the content of chlorophyll according to green algae, blue-green algae, brown algae (diatoms and dinoflagellates) and cryptophytes
Transmission: takes place automatically during each analysis and, if necessary, can be used to compensate the influence of substances which cause turbidity
