The FL23 Algal CO2 Analysis Package is designed for measurements of CO2 exchange from algae in a head space of a plexiglass cuvette (80ml total volume) designed by Qubit Systems. The CO2 gas released into the head space of the cuvette is dried and carried to the Q-S151 CO2 analyzer for measurements of CO2 levels (0-2000ppm) in a flow through system.

Gas enters the cuvette via the inlet port and an air stone which is below the liquid level.  This causes  bubbling through the sample, and generates  mixing action.  The CO2 from the algal suspension is released into the head space above the liquid and exits the chamber via the gas outlet.  Gas coming out of the chamber travels through a PTFE filter and Nafion RH equilibrator before entering the drying column and the Q-S151 CO2 Analyzer.  If any liquid does accidentely leaves the algal chamber the PTFE filter will stop it from entering the Q-S151 CO2 analyzer and Nafion RH equilibrator will reduce the water vapour of the gas to ambient levels.

The illumination of the algal culture is provided by the A113 LED light Source calibrated in software for PAR output in umol photon/m2/s.

Additional Options:

Chlorophyll Fluorescence measurements  can be obtained using the  Cuvette AquaPen (Z985) where the suspension of the algal culture is transferred into a cuvette for the measurements.
