I'm obligated to ask this question of Fermentation Laboratory topic in section Equipping a Fermentation Laboratory, the Design and Preparation of Media for Bioprocesses of Fermentation Technology

Answer 1

The correct choice is (b) Mass spectrophotometer

For explanation I would say: Off-gas analysis can be done with the help of mass spectrophotometer. It is highly accurate but a little bit expensive. Some of the cheaper and low accurate gas analyzers are TanDem, EGAS-L, or FerMac analyzers.
