ADEL - Herstellung von ultradünnen, selektiv-permeablen Membranen mit Deposition elektrisch leitfähiger Strukturen
Ion Mobility Spectrometry (IMS) is an analytical method for rapid on-site detection of toxic gases and warfare agents. An essential component is the sampling system, i.e. the transfer of the gaseous organic molecules into the spectrometer through a membrane. These special membrane inlet systems are to be investigated and improved in the project. In particular, their manufacture is to be facilitated and made process-capable. The primary goal is to develop a robust, industrially processable and cost-effective inlet system that meets the analytical and technical requirements of an IMS. The basis for this is a thin (lower µm range) membrane (polydimethylsiloxane (PDMS)), which can be manufactured reproducibly and is connected to a solid support structure. New membrane inlet systems will be developed and evaluated for the described application.
