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 20 years ago. 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. Today the most recently developed PTR3-TOF instrument reaches limits of detection in the sub-ppq range monitoring semi volatile and even non-volatile compounds. PTR-MS has been successfully employed in many fields of research & technology including environmental research, life sciences, and food science. In 1998 the spin-off company Ionicon Analytik GmbH (www.ionicon.com) was founded to provide PTR-MS instruments to a growing user community and to develop the technology further. Today many research institutions and companies use this technology throughout the world.weiterlesen
