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.

ETH Zurich will be using SUPER SESI for metabolomic studies

ETH Zurich will be using SUPER SESI for metabolomic studies

The ETH Zurich (Switzerland) has recently completed the acquisition and installation process of a new SUPER SESI unit for a Thermo Fisher Scientific Orbitrap mass spectrometer, that will help in different fields of the research conducted at this institution related to metabolomic studies.

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] .

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.

Figshare: make all your research data count

Everyone knows that researching is not an easy task and generates a huge amount of data. However, despite being valuable not all the data resulting from our researches finally come into existence because it is not included in a published and printed poster, paper, article…
