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.

Launching our new ultra-sensitive PTR-QiTOF trace VOC analyzer

Welcome to the future: 25x more sensitive, we proudly present our new flagship PTR-TOFMS instrument: the IONICON PTR-QiTOF.

PTR_QiTOF_webFeaturing a Quadrupole ion guide (Qi), the PTR-QiTOF achieves a performance, no other commercial PTR-TOFMS system has ever been able to demonstrate before.

Expect up to 25x more sensitivity, one order of magnitude lower detection limit and 20% higher mass resolution than the world’s current bestselling and up to now also best-performing PTR-TOFMS instrument – our PTR-TOF 8000.

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.

PTR-MS for indoor air quality monitoring

A new review article discusses important applications of IONICON PTR-MS systems in indoor air quality monitoring.

Many sources of airborne contamination e.g. VOCs (volatile organic compounds) influence on the quality of indoor air. These substances are emitted by household products, electronics such as computers, printers or TVs,  construction materials, wall-paints, carpets, and furniture.  Many of which are known to affect human health or at least to cause unpleasant odors. They can be present in high concentrations due to insufficient ventilation inside closed spaces such as e.g. buildings, offices etc. but also cars and aircraft cabins. Chemical contamination of indoor air is a contributing factor to the so called “Sick Building Syndrome“.

IONICON PTR-MS is an excellent tool for assessing the concentration of indoor air VOCs, providing real-time quantitative results from very low levels (sub-pptv) to high concentrations (ppmv and above).

A new article by S. Schripp et al. discusses various scenarios, sources of contamination and their impact on the indoor air quality. The team of Fraunhofer WKI, Braunschweig, Germany, and IONICON described five applications of PTR-MS in Indoor Air:

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.
