Mass Spectrometry Offgas Multiplexing

BME Systems doubled the number of fermentation units that could be analyzed by an industrial mass spectrometer using valves to multiplex streams that could be sampled at a lower rate.  The valve sets, mass spectrometer and data routing are controlled by a SCADA (Supervisory Control and Data Acquisition) system.  This solution has been in continuous operation since 2011 and was implemented at a third of the cost and half the space of an additional mass spectrometer.
