Participants in the 7th International PTR-MS Conference 2016

This very successful event organized by the University of Innsbruck every couple of years, attracted the community from all over the world for one week full of science and networking. Latest developments were showcased, results discussed and a bright outlook given for IONICON’s real-time trace gas analyzers. (more…)

Visit us at “IABR” and “IGAC” in September 2016

A breath summit and an atmospheric chemistry conference – both communities benefit from PTR-TOFMS and are supported by IONICON

logo_IABR_2016Visit us at the IABR breath summit 2016, at the ETH Zurich in two weeks and experience ultra-sensitive, high-resolution breath gas analysis by PTR-TOFMS! This in combination with the IONICON BET-med sampling interface that is ISO 60601 certified and ready for use in a clinical setting, make our instrument the preferred solution for real-time breath gas analysis.

We’re a proud sponsor for the IABR series of events and will offer live demos during the conference.

logo_igac2016The next major event will be the IGAC Atmospheric Chemistry conference 2016, taking place in Breckenridge, CO, 26. – 30. September 2016.

An international team coordinated by NASA has recently investigated air pollution over the Korean peninsula. Two of IONICON’s PTR-TOFMS instruments were used to monitor volatile organic compounds (VOCs) in real-time aboard NASA’s DC-8 Flying Laboratory. The data gathered by scientists from the University of Innsbruck and Korea’s National Institute of Environmental Research (NIER) will be used to improve satellite-based air quality monitoring over Korea.

Indian PTR-MS collects first VOC data from Indo-Gangetic Plain

Prof. Sinha and his team have compiled a comprehensive dataset from their new high quality atmospheric chemistry observation station at IISER Mohali.

IISER_Mohali_Sinha_team_out_copyright_Vinayak_SinhaProf. Vinayak Sinha lives and does his research in a region called the Indo-Gangetic Plain (IGP). Home of one seventh of the world’s population and as a fertile region, it sustains agricultural food crop production for much of South Asia, yet it remains one of the most under-studied regions of the world in terms of atmospheric composition and chemistry. One of Prof. Sinha’s goals is to change that and being our first Indian PTR-MS customer, he has a powerful tool at hand that he operates on a 24/7 basis together with his team in the new atmospheric chemistry facility “the blue eye in the sky” at IISER, Mohali.

IONICON PTR-TOF-MS helps providing new insights and a SCIENCE paper

Extremely large range of VOCs are a challenge to current emission, air quality, and global climate models.

J.-H. Park et al. were relying on an IONICON PTR-TOF 8000 instrument to study fluxes of an unprecedented number of volatile organic compounds (VOCs) simultaneously. Their results, “Active Atmosphere-Ecosystem Exchange of the Vast Majority of Detected Volatile Organic Compounds“, have recently been published in the prestigious SCIENCE Magazine. Using traditional measurement techniques, monitoring of VOCs was limited to a few selected compounds, the authors explain, whereas PTR-TOFMS technology reveals 186 organic ions with a net deposition, and 494 that have bidirectional flux.

PTR-TOF technology contributes to CLOUD experiment at CERN

New results have been published by the CLOUD team in the prestigious journal „Nature“.

The CLOUD experiment at CERN (European Organization for Nuclear Research) reports a major advance towards solving a long-standing enigma in climate science: how do aerosols – tiny solid or liquid particles suspended in the air – form in the atmosphere, and which gases are responsible? This is a key question in understanding the climate, since aerosols cause a cooling effect by reflecting sunlight and by seeding cloud droplets.

Researchers found out that minute concentrations of amine vapours combine with sulphuric acid to form aerosol particles at rates similar to those observed in the atmosphere. Amines are emitted both from human activities such as animal husbandry, and from natural sources.

The PTR-TOF-MS technology was used to monitor the CLOUD aerosol-chamber by Prof. Armin Hansel and his team, Institute for Ion Physics and Applied Physics of the University of Innsbruck.

Innovative IONICON PTR-TOF-MS technology deployed on NASA atmospheric research aircraft

Researchers on a mission for NASA use newly developed real-time trace gas analyzer from IONICON to measure air pollution in the atmosphere.

What is the quality of the air we breathe? NASA is trying to answer this question using satellite-based Earth observations. By the end of the century, satellite data shall be used for monitoring and predicting air quality, much the same as now for weather forecasting. To understand how air pollutants are distributed within the Earth’s atmosphere, NASA makes use of a new compact proton transfer reaction time-of-flight mass spectrometer (PTR-TOF-MS) which we specially developed for NASA deployment.

The innovative lightweight PTR-TOF-MS delivered data with unprecedented spatial and temporal resolution measuring smallest concentrations of volatile organic compounds in the atmosphere. The instrument was deployed for the first time onboard the NASA P-3B research aircraft during the DISCOVER-AQ mission in January and February 2013 to study air pollution in the San Joaquin Valley in California.
