Abstract

A microprocessor controlled quadrupole mass spectrometer system equipped with a sampling unit has been developed for the measurement of gases and volatile components involved in the fermentation processes. The exhaust gases of the fermentors and some components dissolved in the fermentation broth (e. g. O//2, CO//2, N//2, propanol) were analyzed on-line and filtered samples were taken for off-line determination of certain fermentation products. The concentrations measured were in close correlation with the physical parameters of the fermentations and the biological state of the microorganisms. The results were compared with conventional analytical methods, too. The result of this research and development programme is a complex analyzer-control system which can be used for laboratory research purposes and industrial process control of fermentation.
