PhytoFlash Active Fluorometer

The PhytoFlash is a patented solid-state submersible active fluorometer designed to detect minimum fluorescence (Fo), maximum fluorescence (Fm), and quantum efficiency (Fv/Fm or yield) of phytoplankton. These data can be determined during extended deployments, CTD profiles, or in the laboratory.

Performance Data:

Copper sulfate (CuSO4) was used to inhibit photosynthesis in a green alga (Dunaliella) culture to demonstrate how yield is affected by "impacted" systems. Yield was evaluated using the PhytoFlash active fluorometer. Measurements were taken at 1-minute intervals over a 50-minute period for two sub-samples, a control and an experimental sample. 100 mM CuSO4 was added to the experimental sample at the 4-minute mark.
