The injection of a volatile tracer in the gas flow allowed to describe the residence time distribution (RTD) in a solid substrate reactor. The chromatographic analysis of Dirac impulses of acetone led to identify the fermentor as a first‐order rate system. The evolution of the time constant (λ) of the system versus the gas flow rate gave a flow rate value that permitted a homogeneous aeration of the fermentor.
