calibration
Correction table for the volume of calibration solution to be added into the vessel for the calibration step in respect of
maximum vessel volume.
Note: 1 ml of calibration solution added to the 400 ml cuvette with maximum volume of 465 ml results in final
concentration of 20 µM dCO

in the vessel.
