University Hospital of Zurich use Super SESI QExactive Plus installed by Fossil Ion Technology and Thermo Fisher Scientific.
SESI and ESI (Electro-Spary Ionization) have been linked since the initial development of ESI. Fenn and colleagues already noted that gas-phase species in the counterflow gas were also ionized by the spray. Still today, the routine calibration of mass spectral data relies on ubiquitous plasticizes and other contaminants (i.e. polydimethylcyclosiloxanes, phthalates) that are ionized in regular ESI via Secondary Electrospray Ionization mechanisms.
As you probably already know, current VOC MS analyzers can detect high volatile species, even when they are present in very low concentrations. For instance, in 2009 P. Spanel and D. Smith measured the concentration of ammonia, acetone, methanol, ethanol, and isoprene in human breath using Selected Ion Flow Tube Mass Spectrometry (SIFT-MS)  .
The European Organization for Nuclear Research (CERN) has officially reached an agreement with Fossiliontech through a project supported by Ineustar-Pioneers and Promalaga to develop a data processing system tool incorporating CERN algorithms, in order to create a post-processing server that shares the conclusions obtained by all scientists working on breath analysis with SUPER SESI.
Universitäts-Kinderspital Zürich is one of the main clinical institutions in Swizerland working on the field of breath analysis. Together with other institutions and research centers in the region, they have shown a strong commitment to innovation …
Secondary Electro-Spray Ionization (SESI) uses a nano-electrospray that produces a cloud of charging ions. These ions ionize the vapor molecules that are in contact with the cloud.
The Deep Breath Initiative (DBI) will be officially launching at the ERS International Congress 2018, on 15-19th September in Paris, France.
