Abstract

Volatile metabolites produced by microorganisms can be measured directly in growth media by membrane inlet mass spectrometry (MIMS). A polymer membrane, which allows volatile compounds to pass, is used as the only separation between the mass spectrometer and the liquid to be analyzed. The practical aspects of membrane inlet design are reviewed and recent innovations, e.g. the use of microporous membranes with solvent chemical ionization are discussed. In addition, applications of MIMS to the direct monitoring and identification of volatiles in microbial cultures are described.
