The effect of sample pressures up to 6 bar on the signal of a membrane inlet mass spectrometer was studied with supported and unsupported membranes of silicone rubber. In both cases we found undesirable pressure effects. With a supported membrane increasing sample pressure causes a reduction of the
## Abstract Membrane inlet mass spectrometry (MIMS) has been developed for the onβline monitoring of compounds in a continuous stirred tank bioreactor (CSTB) used to simulate a wastewater treatment plant (WWTP). A mixture of four industrially relevant nitrogenβcontaining volatile and semiβvolatile
