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.

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?

Researcher Prof. Pablo ML. Sinues gets an ECcellenza Grant of the Swiss National Science Foundation

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.
