✦ Synopsis

Using a quadrupole mass spectrometer (QMS), we continuously monitored N2, 02, qr and ethanol in the outlet gas of a batch fermentor. A computer was used to control the QMS, perform correction calculations and account for interferences between some ion peaks. The ability to continously scan multiple peaks and to use N2 as an internal standard provided rapid and accurate monitoring of fermentation performance. Over the range of interest, a linear response was obtained for all the compounds measured by the QMS.
