In order to optimise growing conditions for microalgae, it is important to be able to determine the concentration of dissolved CO 2 within the algal media. Typically, pH measurements are taken in order to indirectly determine the dissolved CO 2 concentration, as some CO 2 reacts with H 2 O to produc...
