(c) Gas-liquid

The Oxygen-Balance method is typically used for measuring the mass transfer coefficient (K_La) in gas-liquid systems. This method involves monitoring the oxygen concentration in the liquid phase to estimate the overall mass transfer rate from the gas phase to the liquid phase. It's widely used in bioreactors to assess oxygen transfer rates during fermentation processes.
