SUPER SESI

Multy center study to diagnose neck cancer with Super SESI

Multy center study to diagnose neck cancer with Super SESI

We just installed a second Super SESI at the National Cancer Research Institute of Italy to initiate the first multicenter study based on this technology to diagnose neck cancer with breath analysis.

Due to its proximity to the upper airways, breath analysis is an ideal non-invasive diagnostic approach to detect this disease at an early stage. We are committed to serving scientists and proud to contribute to the improvement of the health of so many people.

ETH reseachers double their investment in Super SESI.

We have recently installed a new Super SESI and a new Exhalion, that will work in tandem with a Thermo QExactive Plus. This investment validates the technology.

With this acquisition, ETH Zurich (Switzerland) consolidates its position as a top research institution, leading the field of breath research.

Jinan University (Guangzhou, China) pioneers the use of Super SESI in China

Jinan University (Guangzhou, China) pioneers the use of Super SESI in China

We are proud that Jinan University is now using SUPER SESI for breath analysis and environmental analysis.

We hope this new Super SESI Exhalion coupled with the Orbitrap Mass Spectrometer Q Exactive, will allow the IMSAE researchers to focus on their scientific findings, while taking consistency and performance for granted.

Things you didn't know about SESI and ESI (Electro-Spray ionization)

Things you didn't know about SESI and ESI (Electro-Spray ionization)

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.

The relevant role of humidity in Secondary Electrospray Ionization (SESI)

The relevant role of humidity in Secondary Electrospray Ionization (SESI)

Rising the humidity level of the gas introduced through the sample line accelerates the charge transfer reaction rate in Secondary Electrospray Ionization (SESI). It is hypothesized that larger clusters transfer their charge more efficiently than smaller clusters or even bare ions.

The difficulty of detecting low volatility species for VOC analysis technologies

The difficulty of detecting low volatility species for VOC analysis technologies

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] .

Differences between SESI and APCI ambient ionization techniques

Differences between SESI and APCI ambient ionization techniques

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?

CERN's most advanced tools will help Fossiliontech scientists to easily process breath analysis data

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.
