Membrane extraction mass spectrometry for the on-line analysis of gas and liquid process streams

A membrane extraction maw spectrometry (MEMS) tech& que was developed for the on-line analyrk of organlc components of multiple liquid and gas dreams. Sllkone hollowfiber “branos allow for the extrcrctkn of orgalc chedcdr from compkx ad dMy matrices wtth no sampk preparrdkn. MWpk dreams of both air ad water were analyzed orrllne wlth a dngk analyzer. TM6 method has been appUed In an aerobic blologlcal wastewater treatment process. Maw balance determinations were performed by quantltatlvdy measuring HH organlc contaminants In tha lnfiumt wastewater dream, In the effluent water stream, and In the effluent air stream.
