With the development of the ALG control microLAN adds a new technique to the existing iTOXcontrol. This technique is capable to identify classes of algae and to convert fluorescent values into chlorophyll-a concentrations and blue-green algae (or cyanobacteria) concentrations.
The ALGcontrol for algae differentiation uses 7 LEDs for fluorescence excitation. The LEDs emit light at 7 selected wavelengths.
The turbidity and DOM are detected to enhance the accuracy. They will be used to correct the increase or decrease of the signal caused by the presence of DOM and/or turbidity.
