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) [1] .

In the equilibrium, both Secondary Electro Spray Ionization (SESI) and Atmospheric Pressure Chemical Ionization (APCI) generate charged water clusters that act as charging agents. What are the differences bewtween these ionization techniques?

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.

Sinues is a pioneer of the SESI technology and established SESI-MS as a technique for breath research. The goal in the granted project is to optimize the therapeutic regimen of pediatric patients to maximize efficacy and minimize side effects. For this the group will develop a mass spectrometry-based breath test.

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 …

Breath Analysis performed with SUPER SESI is one of the topics of Thursday 22nd November (19.30) Beer for Science talk organised by Uciencia, the Publications and Scientific Dissemination Service of the University of Malaga.

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.
