Because of popular demand we summarised the most important features of the miniRUEDI in a datasheet document: download PDF document
HeliumOne, the Oxford Noble lab, and the University of Dar es Salaam are on the hunt for helium — and they will be using a miniRUEDI!
The foundation of Gasometrix GmbH as an Eawag Spin-Off was well received in the media. Tages Anzeiger and some other newspapers picked up the Eawag press release, and I got interviewed by Swiss Radio and Television for their Science Magazine. Here’s the interview (in German):
Eawag News about Gasometrix GmbH
Analyses of environmental gases which previously required months of laboratory work can now be carried out rapidly in the field. A group of Eawag scientists have developed a portable mass spectrometer allowing on-site measurements – and a spin-off has been created to commercialize the new system. (read the full article)
The following figure shows an m/z scan obtained from a miniRUEDI analysis of ambient air. The electron impact ionization energy of the ionizer (EE) was set to the default value of 70 eV for this measurement. Using lower EE values would reduce double ionisation. This chart is useful to assess the occurrence and importance of interferences of peak signals related to different gas species at the same m/z value.
