Development of masspectrometrical techniques for online analytics in aquatic systems
Membrane-introduction mass spectrometry (MIMIS) is an useful tool for the online and on-site analysis of (poly)aromatic and halogenated compounds in aquatic systems. For MIMS analytes are transported selectively from the liquid phase through a semipermeable membrane into the vacuum of the mass spectrometer, removing the matrix in the process. Advantages, especially by coupling membrane inlets with time-of-flight mass spectrometers and resonance enhanced multiphoton ionization, are the fast analysis as well as the improvement of sensitivity and selectivity for the desired analytes.
