The new IONICON APi-TOF presented at EGU and ASMS 2018

Atmospheric Pressure Interface for the Modular ioniTOF Platform

The flexible and modular ioniTOF-MS platform for research & OEM

The ioniTOF is our modular and flexible, entry-level to high-resolution Time-of-Flight platform, featuring custom interfaces and high-performance IONICON hexapole ION-GUIDEs. All our renowned PTR-TOFMS series products are exclusively based on the ioniTOF. Now we took this concept one step further and developed an Atmospheric Pressure Interface for the ioniTOF.

The “ioni” APi-TOF presented at our EGU 2018 booth

We presented our new “ioni”APi-TOF, which has already been field-tested during the last CLOUD campaign experiments at CERN, at the EGU assembly in Vienna and just a couple of days ago also at the ASMS annual conference in San Diego.


Join us as Early Stage Researcher for the CLOUD-MOTION project

Do your PhD in Environmental Physics (CLOUD Experiment)

Happy New Year! We start into 2018 with a new interesting job offer: join us as Early Stage Researcher (ESR)!

You will be employed for 36 months at IONICON and enrolled in a PhD program at the University of Innsbruck as part of the CLOUD-MOTION MSCA-ITNETN project with the aim to investigate the formation of aerosol particles and ice under precisely controlled conditions that closely simulate atmospheric conditions.

PTR-TOF Technology helps understanding how forests grow clouds

Emissions from forests influence very first stage of cloud formation – VOC concentration in CERN’s CLOUD chamber measured with PTR-TOF-MS.

In a paper published in the prestigious journal Science today, CERN’s CLOUD experiment has shown that biogenic vapours emitted by trees and oxidised in the atmosphere have a significant impact on the formation of clouds, thus helping to cool the planet.

Organic vapor concentrations such as Pinanediol were measured in the CLOUD chamber by scientists from the “Institut für Ionenphysik und Angewandte Physik” of the University of Innsbruck using advanced PTR-TOF technology, allowing for real-time quantification of tiniest concentrations of volatile organic compounds (VOCs).


First results of CERN’s CLOUD experiment now published in NATURE journal

PTR-MS technology made in Austria contributes to important results of the CLOUD experiments at CERN.

The CLOUD experiment has been designed to study the effect of cosmic rays on the formation of atmospheric aerosols – tiny liquid or solid particles suspended in the atmosphere – under controlled laboratory conditions. Atmospheric aerosols are thought to be responsible for a large fraction of the seeds that form cloud droplets.

The CLOUD results show that trace vapors assumed until now to account for aerosol formation in the lower atmosphere can explain only a tiny fraction of the observed atmospheric aerosol production. The results also show that ionization from cosmic rays significantly enhances aerosol formation. Precise measurements such as these are important in achieving a quantitative understanding of cloud formation, an important contribution to climate models.

The prestigious NATURE journal has now published first results from the CLOUD experiment, where two PTR-MS instruments from the Institute for Ion Physics and Applied Physics of the University of Innsbruck contributed to this cutting edge project. A quadrupole based PTR-MS was used to monitor trace concentrations of Ammonia and a PTR-TOF-MS system (based on time of flight technology) continuously scanned organic vapor concentrations in the CLOUD chamber.
