✦ Synopsis
Characterization of some thin (10-50 pm) and selective (zeolite filled) sheet pervaporation membrane materials for the on-line analysis of volatile compounds in solution by membrane introduction mass spectrometry and flow injection analysis is reported. A comparison of the membrane performance, both in aqueous (normal) and organic (reverse) phase, is made using a seven-component test mixture and a triple quadruple mass spectrometer. While no significant difference is observed in the normal phase experiments, reverse phase experiments with the thin membranes showed an improvement in rise times and analysis times by a factor of two.
