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 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.
