PTR-MS (Proton Transfer Reaction - Mass Spectrometry) is a technology developed at the Institute of Ion Physics and Applied Physics at the University of Innsbruck in the late 1990’s. PTR-MS has been found to be an extremely powerful and promising technology for the in-situ detection of volatile organic compounds (VOCs) at trace levels (pptv) in gaseous media. PTR-MS has been successfully employed in many fields of research & technology including environmental research, life sciences, and food science. Almost 15 years ago the spin-off company Ionicon Analytik GmbH (www.ptrms.com) was founded to provide PTR-MS instruments to a growing user community and to develop the technology further. In 2004 Ionimed Analytik GmbH (www.ionimed.com) was founded to provide trace gas solutions for the fields of biotechnology and medicine. Today many research institutions and companies use this technology throughout the world.weiterlesen
