A Novel Approach to Measuring Carbon Assimilation and Chlorophyll a Fluorescence in Algal Suspensions

The LI-6800 Portable Photosynthesis System is trusted by leading researchers and institutions around the world to measure carbon assimilation (A) and pulse-amplitude modulated (PAM) chlorophyll a fluorescence in terrestrial plants. With high precision CO2 and H2O gas analyzers and automated system controls, the LI-6800 is used to test hypotheses at the forefront of photophysiology research.

The new 6800-18 Aquatic Chamber extends these capabilities to aquatic samples, enabling researchers to explore questions related to photosynthesis of algae in suspension.

Jason Hupp, Principal Scientist at LI-COR, will introduce the theory behind the Aquatic Chamber, describe principles of the measurement, and show example datasets. Dr. Tracy Lawson and Dr. Phillip Davey from the University of Essex will join the discussion to share their early feedback and how they have incorporated the Aquatic Chamber into their work on algae and other aquatic samples.
