Predict the Onset of Harmful Algal Blooms

Early identification of harmful algal blooms (HABs) is important to be able to leverage resources to protect public health. CyanoFluor™ is a field-portable fluorometer which quickly performs calculations providing an indication of whether environmental conditions are changing, favoring cyanobacterial production which typically lead to HABs. CyanoFluor provides PC (phycocyanin) to CHL (chlorophyll) ratios for determining relative contribution of the cyanobacterial population within whole phytoplankton populations. Monitoring PC to CHL ratios over time enables users to spot the increase of cyanobacteria as an early indication of HAB development. Predicting the onset of these types of blooms is critical for controlling and mitigating their harmful effects.

Raw water samples can be quickly analyzed with results displayed in less than 30 seconds. Simply insert a cuvette with your sample and press READ. PC:CHL ratios are displayed and logged and can be downloaded at a later time. Raw fluorescence readings are also displayed and can be correlated with µg/L chlorophyll concentrations.

CyanoFluor is factory-calibrated meaning no calibration standards or tools are required; solid-state opto-electronics ensure long term instrument stability. CyanoFluor’s intuitive functions, self-contained design, small size, internal data storage and field portability make it an ideal instrument for HAB monitoring efforts.
