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.

There’s suspense in the air – detected with IONICON PTR-TOFMS

Scientists analysed the air in cinemas and discovered that every movie leaves a characteristic pattern of VOCs

Thomas Klüpfel installs a tube into the ventilation system of a cinema for PTR-TOFMS monitoring.

Researchers at the Max Planck Institute for Chemistry and the Johannes Gutenberg University in Mainz, Germany investigated how the composition of the air changed when an audience watched movies from different genres such as comedies like “The Secret Life of Walter Mitty” and “Buddy”, or fantasy movies like “The Hobbit” and the science-fiction thriller “The Hunger Games”. The scientists determined how the audience reacted to individual movies on a scene-by-scene basis. Using their analyses incl. PTR-TOFMS data, they were also able to reconstruct which scenes were playing at the time. (more…)

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.

VOC release from WPC: a new PTR-TOFMS application

Wood-plastic composites – replacing plastics with wood

Wood-plastic composites

In the quest for new alternatives for crude oil based materials such as plastics, WPCs (Wood-plastic composites) seem to be suitable materials, used in buildings and in the automobiles production. WPC are natural fiber composites with properties of both plastic and wood. It is estimated that the production of WPCs will experience an annual growth of 14% between 2014 and 2019 according to a study by the University of Eastern Finland.

In the study a new sort of additives to the WPC were investigated and the VOC release monitored with IONICON PTR-TOFMS (more…)

Fracking yields high wintertime ozone pollution

New study published in nature – ozone precursor in Utah oil and gas fields measured by PTR-MS

Chemicals released into the air by oil and gas exploration, extraction and related activities (i.e. horizontal drilling combined with hydraulic fracturing “fracking”) can spark reactions that lead to high levels of ozone in wintertime, high enough to exceed the US federal health standards, according to new NOAA-led research, published in Nature.

Winter ozone pollution is surprising because normally, the more intense sunlight of the summer season can spark the chemical reactions that create ozone pollution, said lead author Peter Edwards, a CIRES scientist working at CSD at the time of the study, now with University of York in England. However, Edwards and his colleagues showed that in winter in northeastern Utah, levels of volatile organic compounds (VOCs) build high enough that they can trigger pollution-forming reactions themselves.

HPZAG: new zero-air generator for LCU

With a new add-on, IONICON’s LCU has become an advanced, all-in-one calibration device for trace gas analyzers.

High Pressure Zero Air GeneratorWe at IONICON believe that trace gas calibration is an essential part to support our claim to sell highest accuracy trace gas analyzers. Thus, we have invested in developing trace calibration systems for many years. With the now released high-pressure 0-air generator add-on, IONICON’s LCU has become an advanced, all-in-one calibration device for trace gas analyzers.

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.
