Quadrupole mass filter detectors have been used to get information on the fluiddynamical behavior of bioreactors. To characterize the gas motion, gas residence time distributions have been measured. Complementary, tracer experiments with a volatile liquid material, such as acetone, have proven to give reasonably accurate estimations on the liquid circulation — and the mixing times in pilot scale airlift loop reactors.
